This flat is really very well situated in Lisbon, you can reach every spot very easily by taking the tram which is very close by, really very very practical. Joao is very friendly and we felt really welcome.
Just notice that the sofa bed is not comfortable for 2 adults, it was actually broken but joao has told us about it. And there is a weird smell when taking the stairs to go up to the flat.
Otherwise i advise you to try the artisanal ice creams at the shop right next to the appartment, this is the most delicious i have ever tried =).
