Really nice place to stay. We spent one week with our two kids (10 and 14 years old) at Carla's flat. The flat is very central with only a short walking distance to Metro, busses and tram, but hidden in a quite neighborhood. We never felt unsafe walking in the neighborhood even at nighttime (but we did not feel unsafe at all during our one week stay in Lisbon). The flat is furnished quite elegant. Carla was very nice and friendly, giving us a lot of tips for dining out and shopping. We can really recommend her as a host.
