My wife, daughter and me stayed at Carla's place for 5 days. You can't get an Airbnb more in the center of Lisbon than this one. It's a flat with 3 rooms, and a single bathroom and kitchen for sharing. So we stayed with 2 more people in the flat. Everything is rather small and with low ceilings, but well taken care of and clean. A new set of pans would be good so you don't burn everything you try to fry, but no big deal. The bathroom was clean and the shower nice and warm with good water pressure. The beds were comfy and the first night was quite cold so we asked for another duvet and got it the next day. Carla also recommended to stick the heater on but we preferred the duvet because the air from the fan heater is very dry.
All in all Carla was always responding super quickly and was very friendly.
We would definitely stay there again.
