The location is great, few minutes to the square and various of restaurants. Be ready for going up when you come back to apartment, but it's common case for Lisbon.
There is no door between bedroom and bathroom, so be sure you are ok to such privacy ;)
What was disturbing us the most there were smoking neighbors and the smell during the night, so we had to close window in bedroom even it was hot enough.
The apartment is small but there you find everything you need!
