This is a room of four in dedicated flat for Airbnb guests. There is a shared kitchen and two communal bathrooms. All places were extremely clean and tidy, with locks on the bedrooms doors. The location is nice and 20-30 minutes walking distance to the city centre attractions or you can get an Uber very cheaply (€4 or so). Comfortable double bed, nice room and bathroom. This bedrooms adjoins the communal kitchen but there were no problems with noise. Some other reviews reported noise from construction, but there wasn't anything like this during my stay, so it might be finished now. Luis was also kind enough to send some recommendations for places to eat and see during my stay in Lisbon.
