We spent 4 days in Ana and Antonio's appartement. The check-in went smoothly, the appartement was clean and functional. It is located in a pedestrian street so even if close to the city center, the place is pretty calm. We visited Lisbon mainly by foot and the location of the appartement was perfect. If you want to use public transportation there is a lot of bus, metro and tram lines close by. I recommend this appartement.
