Fantastic place.
Comfortable, spacious and well-equipped - good air-con in the middle of August.
Conveniently close to Ottaviano metro, but slightly removed from the busier road leading up to the St Peters, so it had a quiet neighbourhood feel. Great restaurants in the area too (check out Bistro Luma almost directly opposite).
Roberto was there to greet us upon arrival - lovely guy with good local knowledge. Even in our messages leading up to the arrival, he was super-helpful. Would certainly stay here again.
