We stayed 5 nights in the apartment and can highly recommend the apartment. the location in Alfama is perfect for exploring the city and do sightseeing, the city center is just a short walk away (approx 15 minutes).
The apartment is located in a quiet street (no cars). The apartment is exactly as on the pictures in airbnb and very clean. At night you can close the wooden blinds so it's dark at night.
Communication as well as check-in and check-out with Alessandra was easy and very helpful as she provided us with good advices for restaurants etc. We enjoyed our stay and can recommend staying with Alessandra.
