Good location, good communication, clean and spacious apartment. Two bathrooms which is great, shower did not work in one of them, but we preferred the other one anyways, so it was ok. Nice terrace with view to Vesuvius. Great towels provided.
To climb to the 5th floor was quite challenging for me especially after busy days, but I managed it (and I am 53, out of shape) and it is very clearly communicated, so no surprise.
Overall a nice place to stay, I recommend it.
