The apartment is really nice and right in the center of Lisbon. The room was very clean as were the bathrooms and the other rooms of the house. The street is quite calm and we had no trouble sleeping even if our room's window was on the street side. Great view on the hills !
We'll just recommend to extend the wifi reception because we didn't really have it in the room , and the little lamps on the side of the bed weren't working , but that's really nothing :)
