Anna is a very serious person, she gave us all the informations we needed and waited for us at the room. The flat is very nice and rooms are cosy and very clean, also the bathrooms. Effectively walls are thin so you can hear your neighbours but when we were there it was very calm, also in the street (in february) and we had a very good night. It is very good located, in the beautiful historic district Alfama, with restaurants and bars (the bar at the first floor is nice).
