It was in a great location right by an amazing fado place (tasca do chico) in the center of bairro alto.
My only complaints would be that the walls were really thin and I could hear all the cars and neighbours as if they were in the same room as me.
Over-all it was a good place to stay specially for the price. Bring some ear plugs and it'll be a five star heaven.
Ps: very spacious flat
