Great location, you're in the hearth of Vomero which is always bursting with life, you're also very close to metro so you can go anywhere.
The house is beautiful but needs some love, the furniture's are really old and uncomfortable (chairs/sofa), 2 of the 3 TV there where not working, we could only use the washing machine after washing it 6 times as it had mold smell and stain on the filter, the dishwasher was broken and leaking water... I mean the house needs some investment and update but if you care more about the location, you won't find any issues.
The place itself was very clean, with the exception of the outside garden which was in an abandoned state.
Overall it was a good experience, especially considering that we had to work from home during our 30 day stay, with renovation, the experience could be great.
The host is friendly and available, we managed to get a change of sheets after couple of week and he bring us pastry for the trouble caused by the washing machine.
