We had a great 4 night stay in Alfonso's apartment. It is immaculately presented, spotlessly clean and tidy and very comfortable too. It is a light and airy space on a very quiet complex that feels extremely safe.
There is a supermarket a few minutes walk away and a small convenience store even closer. It is 5 minutes from the metro station (on a hill but that seems unavoidable in Lisbon). It is perfectly located a 10-15 minute walk to the MEO arena (we went to a concert) and 25 minutes by metro into central Lisbon.
Alfonso was a very gracious host, providing lots of information about the apartment and even collecting us at the metro station when we arrived late at night.
We would definitely stay there again. Our favourite Airbnb place so far!
