Mário is very nice and helpful, he prepares all the things we need and want, including foods for 'big breakfast', wine ,beers, et al. And he showed all the things he recommend in a map and told us all the things we need to known(like taxi fees from the airport). The location is on uphill section,quit near by metro within 5 mins walk. The flat is clean and lovely as shown in photos. My family and I really enjoy our stay in Lisbon with Mário's flat.
PS because of the delay of my flight, it let Mário waiting for 2 hours, I am really sorry about that.
