We were welcomed by Joao's wife who was very kind, and told us what we should visit and where to eat.
The apartment is in a very nice part of the city center, with lots of shops and restaurants.
However, the noise from the dog during the nights and the creaky doors upstairs are annoying. We had the misfortune to hear a strange bird (I guess it was a bird) in the morning, too :(
Still, we had a great visit in Lisbon!
