The hotel has 83 rooms and suites. Rooms use soft colors, fine materials, Portuguese details, and a calm modern style. The design keeps the palace mood without making the spaces feel heavy. Many rooms have a warm residential tone, with good lighting, refined fabrics, and bathrooms suited to a five-star city stay.

Entry rooms work well for short Lisbon visits. They give guests a quiet base near Restauradores, Avenida da Liberdade, Rossio, Baixa, Chiado, and Bairro Alto. Higher categories add more space, stronger architectural details, or a better sense of the palace. These are worth considering for guests who plan to spend more time in the room or want a more special stay.

Suites offer the strongest sense of occasion. They suit couples, longer stays, and guests who want the historic character of the building to be part of the daily experience. Some rooms and suites make more of the original palace proportions, while others feel clean, fresh, and contemporary.

Because the hotel is built inside an old palace, room character can vary by category. That variation is part of the charm. Guests who value space, light, or a particular view should choose carefully. The best fit is often the category that balances palace atmosphere with the practical comfort needed for a city stay.

Condes de Ericeira is the hotel's main restaurant and one of its most atmospheric spaces. It sits beneath a striking ceiling and serves Portuguese cuisine with a contemporary touch. The restaurant gives guests a sense of dining inside the palace rather than simply eating in a hotel dining room.

O Jardim Wine Bar is another key venue. It is set in a restored palace hall with a circular bar, large windows, and access to the garden. The menu focuses on tapas, small dishes, Portuguese wines, and cocktails. It works for a light meal, a pre-dinner drink, or a relaxed evening when guests want to stay close to the hotel.

The hotel also has bar and lounge spaces that support the rhythm of the day. Guests can begin with breakfast, return for coffee, spend time in the garden, and finish with wine or cocktails. The food and drink program is compact, but it suits the scale of the hotel and the central Lisbon setting.

Lisbon is full of restaurants, so the hotel does not need to do everything. Its dining works best as a refined home base: breakfast before exploring, a convenient dinner after a long day, or drinks in a palace setting before walking to Bairro Alto, Chiado, or Avenida da Liberdade.

The garden is one of the hotel's most important features. In central Lisbon, outdoor space is valuable, and this palace garden gives the property a slower, more private mood. A century-old dragon tree is part of the setting, adding to the feeling that the hotel has layers of history behind it.

The outdoor pool and pool bar make the hotel especially appealing in warmer months. Lisbon can be intense in summer, and being able to return from sightseeing to a pool and garden changes the pace of the stay. It gives guests a resort-like pause without leaving the city center.

Despacio Spa at The One adds an indoor wellness layer. Facilities include a wet zone, Finnish sauna, experience pool, treatment rooms, and beauty services. The spa uses Natura Bisse products and is designed for guests who want recovery after flights, hills, cobbled streets, and long Lisbon days.

The gym is available around the clock, which helps business travelers and guests with packed schedules. The overall wellness offer is not huge, but it is unusually complete for such a central historic hotel. Garden, pool, spa, and gym together make the property more restful than its address might suggest.

The location is a major reason to stay here. The One Palacio da Anunciada is close to Praca dos Restauradores, Avenida da Liberdade, Rossio, Baixa, Chiado, Bairro Alto, and the Gloria funicular. Guests can reach many of Lisbon's central neighborhoods on foot, then return to a quiet palace setting.

Avenida da Liberdade is the city's main luxury shopping avenue, with boutiques, cafes, hotels, and theaters nearby. Rossio and Baixa give quick access to classic Lisbon squares and tram routes. Chiado and Bairro Alto bring restaurants, bars, shops, and nightlife within an easy walk.

The hotel also works well for first-time Lisbon visitors. It places guests near the historic center but avoids the tightest tourist streets. Alfama, Belem, Parque das Nacoes, and the airport are practical by taxi or public transport. For many itineraries, this is one of the easiest central bases in the city.

The hotel has placed clear focus on sustainability and cultural preservation. It has been connected with Beyond Green and Biosphere certification, reflecting work around heritage, local culture, nature protection, and lower-impact operations. These efforts fit the building, since the hotel depends on preserving and reusing an important Lisbon palace.

Art also plays a role. The Art Gallery at The One presents work by Portuguese artists and adds cultural texture to the public spaces. Combined with the restored architecture, garden, and local dining, it helps the hotel feel tied to Lisbon rather than simply placed in the city.

Service is polished but not stiff. Staff can help with restaurant bookings, transport, local routes, celebration details, and events. The hotel also has meeting and event rooms with natural light, restored windows, coffered ceilings, and access to patios or gardens, making it useful for private dinners and small gatherings.

The One Palacio da Anunciada is best for travelers who want a central Lisbon hotel with history, garden space, a pool, spa access, and strong walking access. It suits couples, culture-focused guests, short city breaks, business travelers, and visitors who want Avenida da Liberdade and Baixa close by.

Compared with Bairro Alto Hotel, this property feels more palace-like and has stronger wellness and pool facilities. Compared with Four Seasons Hotel Ritz Lisbon, it is smaller and more central for walking. Compared with Verride Palacio Santa Catarina, it feels larger and more full-service. Compared with The Ivens, it is less fashion-led and more garden-and-palace focused.

The One Palacio da Anunciada works because it gives Lisbon travelers a rare mix: restored palace atmosphere, a central address, a real garden, pool time, spa facilities, and easy access to the city's main neighborhoods. It is a hotel for guests who want Lisbon close at hand, but still want a calm place to return to between meals, walks, and evenings out.
