I stayed 5 days at Gustavo's place, the flat is really nice, it's in the last floor of a little building, my bedroom was clean , the bed was confortable, there is a desk and a closet and two chairs. The hosts were really friendly and always availaible to talk, they gave me hints about what's is worth visiting and some good restaurants to eat to. There is 3 chambers in the apartment, you can't lock it by key but there are manuals locks to close your bedroom door from the inside or from the outside. The fridge is pretty big so enough place for the 3 chambers, It's a pretty quiet neighborhood, however there are some pigeons that like to rest in the building in front so it can be a little bit to sleep at first, but it's not that disturbing, the only thing that was a downside was that the hot water could take a long time to come in the bathroom, sometimes few minutes, and sometimes it was hot then suddendly cold again and you have to wait again few minutes for the water to be heated again. The apartment is like 10/15min for the nearest two metros, but be prepared to climb those streets ! Lisboa streets are steep ! Thank you Gustavo and Miguel for this amazing time spend at your airbnb :)
