We really enjoyed our week away in Lisbon. The flat was exactly as expected from the photos and Sarah was extremely helpful and accomodating.
In terms of location, we couldn't have asked for much better - it was a mere 10 minutes walk from Rossio in the centre and easy to reach from the airport by metro or taxi. Whilst we had a fantastic time exploring the city, we'd definitely recommend a day-trip out to Sintra (40 mins by train from Rossio), as this was without doubt our highlight of the trip!
