The apartment is great, everything is as described and shown in the pictures. We spent most of our time in the city, but it was great to come back after a whole day of walking to have a nice shower and comfortable bed.
Said that, the real deal of the apartment is the location. You are at max 25 minutes walking form the major sights and still outside of the most touristic areas. It's also a very lively area with tons of restaurants (not the typical tourist traps most of them really authentic). We happily recommend Marcella's apartment.
