The apartment was extremely nice, very very clean and modern. Both the flat and the garden look even better than on the pictures. It is well located in an area where we felt very safe. Tram and buses are just around the corner.
The contact with Ana Maria was very nice even though we didn't meet her personally when we where in Lisbon. Her hostess Vanesse who was very friendly and helpful took care of everything . Check-in and check-out where very uncomplicated.
The only downside we do have to mention is the noise in the flat (which is not Ana Maria's fault)...but you can hear airplanes (which is the case almost everywhere in Lisbon) and more importantly the neighbors who were quite loud since the apartment is located in kind of an apartment complex. If you are sensitive to noises this might be a problem. Otherwise the flat is PERFECT and we were really happy with our choice.
