Absolutely great location for getting to know Lisbon for the first time - walking distance to so many sights and restaurants. Ruben was great about check in when our flight was delayed, and sent a lot of pictures of the building, the apartment, etc. when he was not able to meet us.
The apartment was immaculate and exactly as pictured...that said, note the low ceiling to the interior bedroom (to the right of the James Dean picture) - it is about 5'7" high and if you're a little older, taller and getting up frequently at night, it can be a hazard for head bumps! There is a heavy odor of mustiness as other reviewers have mentioned, but I think can easily be aired out - we found a dehumidifier and fans and they really seemed to help.
The bed was comfy and dark, the kitchen well-equipped and the whole apartment very cozy.
