We enjoyed our stay at João's place very much. The apartment was clean and comfortable, the area around it is calm and safe. João is friendly, helpful and available if you need him.
Lisbon is so beautiful and a lovely place- there are a lot of interesting sightseeings and very friendly people! Also, not very far from the apartment is a really good vegetarian restaurant Graca77.
We highly recommend João's place and hope to meet in Lisbon again.
