Ana's place is a very stylish and well equipped flat in a fantastic location. Although it's very close to lots of great restaurants, bars and shops, it's in a fairly quiet area, so we felt we had the best of both. Very easy to walk to most of the places you would want to visit within Lisbon, and near train stations if you want to go further afield (eg to Sintra). Arrival etc was all very straightforward and Ana was quick to respond when we contacted her with questions.
It is worth being aware that the bathroom is tiny, so some people might struggle with that. But overall we would stay here again because everything else about it was great and we had a fantastic time in Lisbon.
