Sergio was very welcoming - he was there at the flat to meet us and was very helpful with some great suggestions of where to visit in Lisbon and his favourite restaurants (all great recommendations). He left us some wine which was a really nice touch. The flat is lovely and the view is really beautiful. He and Filipa have great taste in decor! Nothing to do with Sergio but there was some construction work next door which is not too loud but started around 8am on Saturday morning (nothing on Sunday). Don't think it will be lasting very long though.
