Very nice stay. Communication with Gigi was easy before arriving to Napoli, for check-in and check-out. He was very thoughtful and dropped by to give us a Prosecco bottle. Safe and quiet building, with elevator and friendly italian-speaking caretaker. Right next to the line 2 and funicular station. Easy access by foot to the seaside and Chiaia restaurants (you have to go eat a pizza at Gino Sorbillo's !). 30 min walk to Piazza del Plebiscito.
Quiet appartment once the windows are closed (the neighborhood is quiet compared to historic center, but there is a bit of traffic on via del Parco Magherita). Large and confortable bed on the mezzanine. Altough we did not really need it during our stay, the air conditioning seemed to work perfectly and should be really appreciated during hot summer days.
In conclusion, I recommend this place ! Thanks Gigi !
