We arrived late in the evening and we found the building very easy, but then you have a choice of 10 ringing bells so it's not clear which one to take. It's a nice & spacy apartment with a perfect location to visit Lisbon. The metro and the center of Lisbon are in walking distance. The apartments in the building and the streets in front of the apartment are quit noisy, but still ok. The beds are good and some things could be more clean, but we had a good stay!
