The flat is situated in a calm area. It was very clean and had enough space for us 4 people. The beds very comfortable and the kitchen was well equipped, so we could easily cook almost everything we wanted to. At the time of our stay it was very hot and the flat had no ac, but three fans so it was okay to stay there in the days.
The metro is 5-7 minutes away and supermarkets the same. We recommmend the little restaurant „Nikola“ In the street „Rua Marques da Silva“ close to the flat, that was very cheap and tasty :)
Also we recommend to stay in the flat, it was very good for a city-trip to Lisbon.
