Why book The Delphi Hotel in Downtown LA?
The Delphi is worth booking because it turns a genuine mid-century landmark into a boutique hotel with more room and more character than its price point suggests. The building at 550 South Flower Street is the Superior Oil Company Building, a marble-clad high-rise designed by Claud Beelman in the Late Moderne style and built in 1955 to 1956. It became The Standard Downtown LA in 2002, closed in 2020, and reopened in 2023 as the Delphi, an independent hotel that has kept the marble lobby, the generous floor plates and the rooftop while shedding the previous brand. The result is a hotel that reads as a piece of Downtown history reinvented rather than a generic conversion, and the biography of the building, from oil-company headquarters to Standard to independent boutique, is part of what you are booking.
The practical case is straightforward. Because the tower began as offices, the rooms are noticeably larger than most Downtown counterparts at the same rate, and the rooftop pool gives the property a social heart that the financial district otherwise lacks. It sits at the corporate core of Downtown, two blocks from the Westin Bonaventure and within walking distance of the Convention Center, which makes it a natural base for business as well as a value-minded weekend. Set expectations for a characterful four-star independent rather than a full-service luxury hotel, and understand that Downtown quietens sharply at night, and the Delphi makes a strong case for the money.
What are the best rooms to request?
Request a higher-floor room with a Downtown-facing outlook, and value the space, because square footage is the Delphi's quiet advantage. The 205 rooms and two penthouses sit on the old office floor plates, so even the standard categories are larger than most Downtown rooms at the price, with Egyptian cotton sheets, down pillows and the building's original marble surfaces carried into the bathrooms. The categories run from standard up through superior and deluxe to the two penthouses, and the meaningful differences are floor, view and space rather than a change of finish. The upper floors trade the street for the skyline, and the two penthouses are the best rooms in the house for anyone who wants the Downtown view from the room as well as the roof.
The honest caveats fit a four-star independent in a converted tower. The design is characterful but not flawless, some of the mid-century bones show their age, and the service is friendly rather than the polished five-star operation you would find at the Ritz-Carlton a short drive away. Downtown Los Angeles is busy and commercial by day and can feel quiet and empty at night, so this is a location that rewards guests with a daytime reason to be here rather than those looking for an evening neighbourhood at the door. Book a high floor for the view and the quiet, use the space the rooms give you, and set expectations for value and character over luxury polish.
Ask for a high floor facing the Downtown towers for the skyline, and head up to the rooftop for a drink at UCA Terraza before dinner while the light is on the buildings. Denae's downstairs is the easy option for a late or early meal seven days a week, and if you are driving, confirm valet or the nearest parking structure at booking so you are not circling Flower Street on arrival.
What are the restaurants and bars at The Delphi?
Dining is spread across three distinct rooms, which is generous for a hotel of this size. UCA Terraza is the rooftop bar and restaurant, with skyline views, seasonal craft cocktails and shareable plates that lean West Coast, and it is the property's showpiece and the reason many locals come without staying the night. Down at street level, Denae's is an indoor-outdoor retro diner that serves breakfast, lunch and dinner seven days a week, which gives the hotel a genuine all-day, all-price option that most Downtown hotels lack. The lobby also holds a coffee and cocktail bar pouring La Colombe, staffed by baristas who turn to bartending as the day goes on, in the lobby or on the sunken outdoor patio. Between the three, the Delphi covers a rooftop night out, a casual meal and a working coffee without leaving the building.
Does it have a rooftop pool and a gym?
Yes. The rooftop pool deck is the Delphi's social centrepiece, framed by panoramic Downtown views and planted as a garden rooftop rather than a bare concrete deck, which is the detail that separates a thoughtful conversion from a repurposed office block. It gives you the Downtown panorama from a lower, more relaxed vantage than the tallest towers, which suits guests who want the view without the height. There is also a 24-hour fitness centre for early or late workouts. The Delphi does not run a full destination spa, so travellers who want extensive treatments should plan on booking those elsewhere; the wellness offer here is the pool, the roof and the gym rather than a spa floor.

UCA TerrazaHow does The Delphi compare with the other Downtown LA hotels?
Against the field, The Delphi is the characterful, value-minded independent in the Downtown core, and the choice comes down to how much service and polish you need. The Ritz-Carlton, Los Angeles at L.A. Live is the full-service luxury benchmark Downtown, the pick if you want a five-star operation, a spa and a high-floor view. Hotel Figueroa is the other characterful independent nearby, a Spanish Colonial landmark with a strong pool scene and its own history. The Westin Bonaventure is the John Portman glass-cylinder icon two blocks away, larger and more corporate, built for conventions. The Delphi's own trade-off is that it is a four-star operation rather than a luxury one, and the financial-district address is quiet after dark.

Frequently asked questions
What was The Delphi Hotel before, and when did it reopen?
The Delphi is the former Standard Downtown LA. It occupies the Superior Oil Building, a marble-clad high-rise built in 1955 to 1956, which became The Standard in 2002, closed in 2020, and reopened in 2023 as the Delphi, an independent hotel that keeps the building's mid-century bones.
Where is The Delphi Hotel and how many rooms does it have?
The hotel is at 550 South Flower Street in Downtown Los Angeles, in the financial district two blocks from the Westin Bonaventure. It has 205 guest rooms and two penthouses, and the rooms are notably larger than most Downtown counterparts because the original office floor plates convert to generous layouts.
What are the restaurants and bars at The Delphi?
UCA Terraza is the rooftop bar and restaurant, with skyline views, seasonal cocktails and shareable West Coast plates. Denae's is an indoor-outdoor retro diner serving breakfast, lunch and dinner seven days a week. A lobby coffee and cocktail bar pouring La Colombe rounds out the food and beverage offer.
Does The Delphi Hotel have a rooftop pool?
Yes. The rooftop pool deck is the hotel's social centrepiece, framed by panoramic Downtown views and planted as a garden rooftop rather than a bare concrete deck. There is also a 24-hour fitness centre. The rooftop is a lower, more relaxed vantage than the tallest Downtown towers, which suits guests who want the view without the height.
Is The Delphi Hotel good for a business stay?
Yes. Its financial-district position, oversized rooms and meeting space suit extended business stays, and the rooftop bar gives a client-drinks setting a convention hotel cannot. The trade-offs are a four-star rather than a full luxury level of service, a Downtown location that is quiet at night, and valet or nearby-structure parking.
