The room in Lisbon is perfect for a short stay in Lisbon. Very close to the city centre, very close to Bairro Alto's nightlife. Nuno, the host, was very nice and helpful, he left us wine, oranges and organic coffee and he also gave us a lot of helpful and cool tips.
As a short note: the bed is quite small and the room isn't very well vent and doesn't get a lot of natural light due to the fact that it is in an old typical Lisbon building at the ground floor.
But, beside this, this apartment is really nice.
