We booked this apartment because of very good reviews and Enrico's superhost status but in fact we had a mixed experience. Enrico was indeed very responsive and helpful, he gave good advice regarding sightseeing, shops and restaurants. But it was cold in the apartment when we stayed there in January, and the only heating was by two aircons in two bedrooms. It was too cold in the third bedroom and sitting room.
The location could be great but there was very loud music till late right under our windows because of some festivities in the square. Of course they don't happen every day, but when they do, you really have to run away. Enrico provided only one set of keys for the four of us, and the keys cannot be removed for the aircon/heater to keep working. This means if one person leaves, he/she cannot get back in without someone having to go downstairs three floors to open. This is simply unacceptable.
The building is quite old and although Enrico did a good job equipping the bathrooms, the hot water still comes only after a while and takes time to leave the sink.
In short, if you come in mild weather and can do without aircon/heating, if there are no festivities in the square when you are there, if you don't mind running up and down the stairs to let people in when they step out - then you can really enjoy the location and Enrico's warm hospitality. But there are too many IFs for a perfect mark
