The apartment was really nice and big and light. We were all adults in Lisbon for a wedding so itnsuited us perfectly. It felt like we all had our own space while being able to sit together in the living room.
The location was good - easy get to from the airport, right next to a metro station and only a 20 min walk to Alfama if you prefer a stroll through the city.
There were difficulties with the gas supply and therefore our hot water while we were there but Duarte was really good at replying quickly and dealing with the problem.
