Just back from an amazing week holiday in Lisbon. The apartment was absolutely perfect for us - we had everything we could possibly ever need. Location is brilliant, less than 5 minutes to the metro and about 30 minutes to the main train station.
Felt very safe all the time. Communication was really good and the organised transfer was a lovely touch.
It is at the top of a steep hill and has no lift so may not be the best for small children but Lisbon is very hilly in general so would be hard to escape this in most places.
We would love to return next year and would definitely recommend.
