My wife, mother-in-law and I loved our 1-week stay here. It's right in downtown Lisbon / city centre and 400m (6-minute walk) from Praça do Comércio. It's 1 floor up from the ground floor and the building has an elevator, which is perfect for senior citizens or people bringing large maletas. There's a mini supermarket right across from the building and a Michelin rated restaurant on the ground floor of the building. The windows are good quality so you don't hear the noise outside when closed despite the busy pedestrian street around the entrance. Highly recommended.
