The apartment was perfect - everything we expected and more. The location was great - within walking distance of many tourist attractions as well as just a few steps away from a host of pubs, bars and restaurants. The area is not the most touristic, but this was something we really liked as we wanted to get a proper feel for the place which we feel we did. The locals were friendly and keen to help us get the most out of our time in Lisbon. We really enjoyed our stay.
The only "negative" thing I can say is that we did not get to meet Leo during our stay - we were instead met by his friend, who gave us some good tips. This was not an issue, just something to bear in mind.
The apartment is large, clean, and better in real life than in the pictures. Highly recommended!
