The flat is really well located and everything is brand new. Rosario is a top host, the communication via WhatsApp was very convenient with him. I would recommend this flat to everyone and come back again every minute, because the mix between price - location & furnishing is one of the best I have seen in Naples so far. There is also a whole folder with recommendations and information for Naples which we can approve.
However there are some little things that quite don't make it for me to be the top notch accommodation you can rent: By entering the flat you quickly recognise that this is a flat that is only rented part time to people and no body has lived there ever before. The TV in the living room is to small to watch anything on it, because the size doesn't relate to the distance of the big couch in the living room. When you are with 4 people you wouldn't sit in the living room because its not cozy enough - a carpet, some side table and an armchair are missing and would give the room a much better atmosphere. There are two bedrooms, one has a double bed and one has a couch sofa which is quite uncomfortable to sleep on for more than two nights. The second bedroom is big enough to put another proper bed in, why not do it? There will be enough space for a baby bed anywhere else in the flat. We went in February so the temperatures in Naples are quite low. Since all windows, beside the kitchen windows, are only single glassed from wood which connects to the ground or the raw stone without any isolation, there is some airflow in the flat which will make it rather cold while sleeping. Here it is also the question, why is the kitchen window exchanged to an isolated one, when you really don't need it in that room. Also by this single windows the noise from other flats is on a quite Italian level. The bedroom windows have shutters, which helps a little bit. In the bedrooms there are double adapters for the sockets missing, because you cannot charge your phone and use the bed table lighting at the same time.
The big plus of the flat are the two bathrooms - which (as some people before wrote) have no connection/hole between them anymore. There are also two balconies, one big and one small one. The big one should be very nice to sit on in summer. Also the door lock is very safe with big bolts, so nobody will be able to break in.
As a summary we really felt good staying in this flat and hope that it will be, with some minor changes, converted to the best place Naples has to offer.
