I've stayed at Elena's place for about 10 days. Elena was super responsive and friendly host who met me at the very last minute due to an issue with another place where I had to cancel my reservation.
The house was on the second floor, with great direct sunlight during the morning!
Quite spacious and clean apartment, exactly as shown in the pics. Everything was working fine, nothing really to complain about... good hot water, furnished kitchen, clean towels, and included toiletries.
The apartment was in a great location next to bars, a very big market, grocery stores and not too far from Ottaviano subway station.
To note that the heating is not controllable from the apartment, but remotely by the host, which is super willing/helpful in accomodate your requests anyway.
I would definitely recommend it and stay there again!
