There are many good things about this apartment. Filipe is an outstanding host, the location is brilliant, the apartment itself is very nice and has everything you might need. In those respects it's great.
However, there is one negative: sound insulation. The walls are extremely thin and you can hear almost everything from the neighbours. The main bedroom, for example, seems to be next to the bedroom of a young baby, who at the moment is crying every few hours during the night and woke me up each time. To the point where I had to listen to music to block it out and was very tired during the daytimes as a result.
That aside - and I guess there is little Filipe and Sofia can do about it - it was a positive stay and I am grateful to Filipe for his excellent hospitality.
