Architect Ludwig Heim designed the building, completed in 1889, with a neo-Renaissance facade that still anchors this side of the square. The hotel retains the scale of a major financial institution: tall windows, generous internal volumes, and formal architectural details. Its most distinctive spaces follow the bank's original arrangement, with former offices used for accommodation and the principal hall serving as a gathering place. Many of these rooms retain the height and generous proportions of the bank's working spaces.

The 145 accommodations comprise 106 rooms, 26 Grand Rooms, and 13 one-bedroom suites. Superior Rooms measure 35 to 38 square meters and face the city or courtyard, while 38-square-meter Premier Rooms look directly onto Bebelplatz. A king bed or twins is available in both categories. Deluxe Rooms offer 38 to 40 square meters and allow a third guest with an extra bed; Superior Rooms accommodate two. Grand Rooms have an open studio layout; the Premier One-Bedroom Suite separates living and sleeping areas across 60 to 65 square meters, with a balcony and walk-in wardrobe.

For outdoor space, the Terrace One-Bedroom Suite pairs a 45-square-meter interior with a furnished terrace of equal size. The 62-square-meter Historic Grand Room occupies a former director's office with original wood paneling. At 200 square meters, the Presidential Suite adds a dining room, kitchenette, separate service entrance, and a balcony running its length. Selected connecting rooms support family stays, subject to availability. Mosaic bathrooms have underfloor heating, a bathtub, and a separate walk-in shower.

De Rome Restaurant follows a contemporary Italian direction, with homemade pasta, fish, and dishes that change with the seasons. It serves breakfast as well as lunch and dinner, and its wine list accompanies a menu grounded in recognizable Italian cooking. In summer, the Secret Garden extends dining outdoors. The restaurant's elegant-casual dress code suits its position beside the opera without requiring a formal evening on every visit. Vegetarian choices are available, and the kitchen accepts advance discussions about allergies and dietary requirements. In-room dining provides another option when an early departure or a quiet meal makes a restaurant visit less convenient.

De Rome Bar overlooks Bebelplatz and serves cocktails with light dishes. Its Opera Drinks take inspiration from productions at the neighboring State Opera. Upstairs, the Rooftop Terrace combines cocktails with stone-oven pizza and seasonal food. This is an open-air venue with weather-dependent, seasonal operation, so the indoor bar remains a separate part of the hotel's evening life.

The Spa has five treatment rooms, including a room for couples, with massage and facial treatments using myBlend skincare. Its thermal area brings together a Finnish sauna, steam room, Kneipp foot baths, and an ice fountain, followed by spaces for resting between treatments. The arrangement allows for a dedicated spa visit as well as an appointment during a city stay. External guests can also book treatments or day-spa access; this is not an exclusively residential facility. The treatment menu also includes manicures and pedicures, allowing grooming appointments to be combined with time in the thermal area.

A 20-meter indoor pool occupies the bank's former jewel vault. Marble columns and mosaic tiles surround the water, with low lighting emphasizing the enclosed architecture. It is a substantial swimming facility within a central city hotel, with enough length for a proper sequence of laps. The fitness center has cardio equipment, free weights, and barbells, and personal training can be arranged. Gym access is available around the clock, independently of the pool's opening schedule.

Families are supported through a children's program covering babies through teenagers. Younger guests have child-sized bathrobes and slippers, while older children can receive itineraries prepared by the concierge. Babysitting is available on request, allowing parents to arrange an evening at the opera or a restaurant reservation. For a family exploring Berlin together, these smaller arrangements can matter as much as the choice of room, especially when ages and interests differ.

The Grand Ballroom occupies the former banking hall, retaining its stone-mosaic floor beneath a glass ceiling approximately 10 meters high. Daylight and chandeliers illuminate a room that accommodates up to 250 guests. Five smaller meeting rooms also receive natural light, with spaces suited to gatherings of up to 90. A separate event entrance helps distinguish these occasions from everyday hotel arrivals. For an outdoor private dinner or reception, the fifth-floor Hedwig Terrace accommodates up to 40 guests. It sits one level above the main Rooftop Terrace and is reserved for private functions.

Some of the smallest surviving spaces carry as much character as the ballroom. An original strongroom, approximately 25 square meters, can be used for private events behind its heavy circular vault door. Gold mosaic in the pool area recalls the valuables once stored here, alongside dark tiles that evoke the former safe-deposit boxes. Elsewhere, sandstone balustrades and stucco preserve the bank's formal architectural vocabulary. Up on the roof, the view reconnects the hotel with Berlin: the State Opera, Berlin Cathedral, television tower, and the roof of St. Hedwig's form a recognizable skyline. These are views from the public terrace, not an outlook promised from every bedroom. The building's enclosed historic interiors and its elevated outdoor spaces both contribute to the experience of staying here.

The hotel entrance is at Behrenstrasse 37. Its published driving estimates are about 50 minutes from Berlin Brandenburg Airport and 10 minutes from Berlin Central Station, with traffic affecting both journeys. Taxis provide a direct arrival from the station, and parking can be arranged at Q-Park Operncarree. Once luggage is settled, the surrounding square and cultural buildings make an immediate starting point for exploring Mitte on foot, without needing a car for every outing.
