Great stay at Isabelle's place, the location is superb - Bairro Alto is a fun area and its easy to walk to all sorts of bars, restaurants etc both there and the nearby neighbourhoods, and to get access to the various public transport options. All communications were fast, helpful and accurate, check in / out no problem. Plenty of helpful advice from Isabelle.
The stairs are pretty steep so not really suitable as a place for anyone with mobility issues. Spacious apartment for two people on two floors, well equipped, clean, all round an excellent base for visiting Lisbon.
