Very modern apartment, seems to be remodeled recently, bright colors, a lot of light in the living room and kitchen area, fully equipped kitchen, nice bathroom, AC works fine, you need it! Not because it is extremely hot outside, but the apartment warms up easily, probably because it is top floor and a lot of sunshine all day.
Elevator did not work! It is 2 floors up, not really a problem, only with luggage a little irritating;
Perfect location, in the centre of the old town, trams are within 3 minutes walking distance, big supermarket is very close, bakeries, restaurants, tourist sites, actually everything is very close; seems to be a very safe area; we never felt uncomfortable;
when you have a car it gets tricky, if you are lucky you will find a parking lot on the street, street parking is cheap but time limited (maximum 4 hours!), a more expensive parking lot is close;
We definitely recommend the apartment and on our next trip to Lisbon we would love to stay there again
