The hosts are nice and friendly. We booked them in the train on its way to Lissabon and they replied within half an hour and waited for us when we cam from the train.
Very good spot : 5 minutes from the Railway station and in the middle of the old part of Lissabon with nice streets and restaurants. Also the view from the window was right on the market wich is there every saturday and tuesday. Nice place to stay, no noice at all from neighbours.
