The flat reflects the description and the photos published, and is located in a very convenient area to visit all the centre of Naples and also the Vomero that can be reached by funicular from Montesanto. The fact that it is on the top floor and in the upper part of the Spanish quarters means that there is plenty of light and air. The location is really excellent. Also, we didn't feel that, despite the reputation, the area was dangerous or unsafe even at night and we would recommend the flat to families with children like us.
Check in went very well with a person coming to look for us as we were lost (GPS reception is not great in the backstreets of the Spanish Quarter and it's not easy to get around by car, at least not for us).
The cleanliness on arrival was not spotless and there was no soap in the bathrooms. Given the ready availability of the agency in charge of the flat we are sure they would have provided it if we had requested it but we found it was easier to just buy it in a nearby shop.
The shower in one of the two bathrooms did not work (no water coming out).
A source of unnecessary irritation is the fact that the owner of the flat, presumably to limit abuse of the air conditioning and electricity by clients, has installed an electricity shut-off system similar to that found in hotels. The problem is that the system is rather rudimentary and when you return home after dark, it is not easy to insert the small key into the main switch. When asked to give us a spare key to avoid having to do this, the agency waited a couple of days and only gave us the key the night before our departure. We would advise the owner to find a better solution.
We don't want to scare off potential clients with this review, the flat is really nice and well located and we really recommend it but the host should try to improve the service even more for a better experience.
