Paulo's flat is great ! Extremely well located in the center of the Barrio Alto district, next to lots of bars, little restaurants and 5 min walking from Chiado/Baixa which is also a very nice and trendy area.
The flat itself is great : very well equiped and clean.
We couldn't have rented a better place to enjoy a long week-end in Lisbon !! We highly recommend this place !
As for Paulo, he is a great host : very nice and helpful. He recommended us lots of nice places in Lisbon and told us about things to visit during our stay.
