We had a wonderful time at Sobiya's flat which was perfectly clean, comfortable and very well located to go sightseeing.
Even though the second part of the escalator was out of order during our stay from August 17th to August 24th, if you are ready to book her flat on the fourth floor with no elevator, the view from the flat is fantastic and worth it. We would definitely come back to her flat for our next stay in Lisbon !
