We had a great stay at the apartment in April. The rooms are a good size as are the living space and kitchen (although we didn’t really use them as we were out exploring Lisbon).
We stayed with both sets of parents and they were fine with the two flights of stairs to the apartment.
Joana assisted with booking a taxi from the airport - you could also get an Uber.
We ate at Atalhol Real and also Barrio do Allivez locally - both were great.
Just a small note that planes do fly over head from the airport so if you are a light sleeper (like my Mum) you may find these wake you up in the morning. Everyone else in our party was fine.
Barrio Alto is a great location for restaurants and bars.
Thanks
