Excellent service in combination with great location

The hotel is very comfortable and modern from inside (recently renovated) whilst in a traditional historic building. The service provided by the reception staff with a smile was excellent. I loved their flexibility in enabling my visiting guests park their car in the hotel garage.
Breakfast service is very good too. The choice of items on self service bar plus on menu provide a great range of choices.
Hotel is well located within easy walk from Sao Bento Station

We stayed for three nights and had a great time. Highly recommend this hotel and we would love to stay here again on a future trip.
Location was perfect, next to City Hall and a lovely downhill walk or 5-minute Uber ride to almost all the major tourist sites. It's 4-block walk from Sao Bento train station. There is a new subway station directly in front of the hotel, making it easy to get to the hotel and many other places in the old city, and which also gave us a short, reliable trip to Camphana Train station on our final day.
Room was large and comfortable. (We had Room 305 in the center front of the hotel.) LOTs of drawers and cabinets to unpack into. Plentiful power outlets and USB ports. Bathroom, was huge, including the shower. Housekeeping was very diligent. We were right next to the elevators but the door and walls were thick and we never heard our neighbors or noise in the hallway. The reception staff, particularly Catia, were outstanding at reaching out to make sure we had everything we needed, including going to great effort to arrange a last-minute winery tour.
Breakfast combines a very large and delicious cold buffet plus a-la-carte table service for hot drinks and food. Restaurant staff were fantastic, particularly Sara who remembered our preferences from day to day and ensured prompt, precise service when we were raring to go out to hit the tourist sites.
Another highlight was the cozy, fun, speakeasy-inspired Bar Américain, where Tiago the head bartender makes inventive specialty cocktails that are amazing. During our stay we had four or five of his creations and they were memorable and delicious. He made us feel as welcome as if we were in his own kitchen.
This was our first trip to Portugal and so our Portuguese was rudimentary, but the staff were all extremely proficient in English and we felt totally at ease. WiFi was great and we streamed a TV show one night on our iPad as we went to sleep.
The only issue was that insulation on one window had lost its insulating edge and so we could hear all the noise from the street and plaza -- which was setting up for Christmas concerts, so there was loud banging from 10 a.m. to 9 p.m. -- but since we were rarely in our room at those times it wasn't the end of the world. The front desk offered to move us to the rear of the hotel but we declined.
5/5
A true grand hotel
