I had a wonderful stay at Sara and Sergio's apartment in Barrio Alto.

Their response to my booking request was very prompt, and they gave me excellent directions to the apartment from the airport. Sergio met me at the apartment, and gave me a comprehensive tour.
They have put together a local map, with handy reference points near by, supermarkets,groceries,metro stations etc.
Barrio Alto is a vibrant exciting part of Lisbon, I would thoroughly recommend a visit to Lisbon, and this apartment was a great base to soak in the sights.
