We had a great stay in Lisbon. We were received warmly and got a lot of tips for sightseeing. Due to the heavy rainfall of last week the apartment had some visible damages. The apartment is located at a unique place, it's touristic but in the evening and at night we had no nuisance of it.
There were noisy and loud guests in the upper apartment for two days, we could hear every word they said. So take into account that it is an old building, it had pros and cons. But for us it had more pros and we would recommend Amalies & Marinhos place.
