We had a great stay at Graça’s apartment. It is a very nice apartment in a great location.
Two things to be mindful of: be prepared to do a lot of stair climbing as the apartment is at the top of building and there is no elevator, some of the ceilings are quite low and people over 1m90 will have trouble standing straight in some of the apartment.
Apart from this there is no reason not to stay here. The host provided us with a lot of information on the city, arranged pick up from the airport and a taxi ride back. She was very responsive to texts. A great place to stay!
