The Appartement had a great location for us, we could see many sights by foot and it is very cool to live in the Alfama neighborhood. Also there is a bus stop very near by, from where you can easily reach further places in Lissabon.
Moniece was very helpful with check-in, Tipps and always reachable. We found the apartment without any problems. I recommend using Uber for transportation from the airport, it cost us a little over 10€ and was fast and comfortable.
You should only know, that living in a building in the middle of Alfama also comes with the noises (and smells) of the direct neighborhood. It can be loud during the night, as everything is very close and the buildings are old.
