The apartment is located in a super nice area, great restaurants nearby, close to the train station where you can take a train to the beach in 35 min.
The apartment is very small, and if you have a tendency of being claustrophobia then you might have it in the bedroom. Is at the end of the apartment, with a window that outlooks a small shaft where the air conditioners are located, that means that there are no windows to open.
We did not sleep good in this bedroom neither the bed, my back hurt after two nights. But overall the apartment is good for a couple of days in Lissabon, and the communication was good with the host was very good. Maybe it was just us?
