I really enjoyed my stay. The flat is beautiful and has everything you might possibly need. My only issue was that the apartment was a little bit untidy and the bathroom had some kind of mold in the corner (just a little bit though, didn't really bother me). The location is also great - Portuense might seem a little bit dirty and boring, but it's actually pretty peaceful and quiet, there is no turists and it's easy to commute to the center of the city or the Vatican. Totally would recommend
