Helena's flat is very cute and comfortable, we had a great experience there! The location is perfect: it is very close to the Barrio Alto (where you can find a lot of bars and restaurants!) and it takes less than 20 minutes to go to Baixa and the Castel de S.Jorge. Helena is very kind, when we arrived she was waiting for us at the apartment with lots of advices for things to do and see in Lisbon and a list of restaurants that she likes. For example the small restaurant of the neighbour: we had lunch there once and everything was delicious! For our next trip in Lisbon, we'll definitely choose this flat again!
