This is a great apartment for a couple, possibly small family. We worked mostly with the host's mother and she was very helpful and readily available for communication. I will warn that the apartment is up several narrow stairs on I believe the 3rd floor, so pack light ! Also, follow the hosts instructions to find the apartment, we trusted a search engine and wound up on the wrong side of Alfama, luckily Maria was very patient as we missed our planned check-in window by quite a lot. Lesson learned: Listen to Maria ! The apartment is very close to the train station which makes access to the airport and the rest of Lisbon a breeze. You can also walk, if you are adventurous, to several key sites in the city.
The only con to the apartment is the person upstairs. Due to the construction of the building you can hear them walking around as if they are in the same room. (No fault of the host) Light sleepers be aware! We had earplugs and a white noise app that helped
