We stayed two nights at Thierry's appartement. Airbnb made an error beforehand and Thierry didn't reveive our reservation or messages. But when we called him, he resolved everything quickly and we could check-in without any delay. The place is roomy, well equipted and clean. Only the air con was big and made some noise but since it was around 38° outside this was a small price to pay. If you carry luggage we would recommend
taking the tram from the metro station, because his place is up one of the many hills from Lissabon.
