The apartment was really nice, modern and clean. The only downside was the WiFi, which worked only in the bedroom.
The location was great, very close to the underground station of Rato (so easily reachable from the airport) and to Bairro Alto (great nightlife). Most if the attractions were by walking distance.
We had difficulties in getting in touch with João. To organize the check-in we had to ask for the help of the Airbnb staff, which urged João to answer. Once we finally managed to hear from him, he was very kind and helpful.
