The house was sparkling clean. The host was very fast to communicate. Although you must take many stairs, Lisbon is the city of seven hills!
The location is in between Alfama and Bairro Alto/Chiado, giving you relatively quick access to the more historic side of town as well as the popular shopping area. We were able to walk most everywhere, including the train station. You can literally see Rossio Square/Train Station outside the living room window.
We had our 3 children with us and the space was very comfortable for our entire family.
