This appartment is amazing! You can divide it in two parts: one has a balcony on the rear side, a double bed, bathroom with shower and extra bed on the mezzanine. The other has the kitchen, a bathroom with shower, the living room, the main balcony (with a nice view on distant mountains (not the Vesuvius)) and a double bed on the mezzanine. The appartment is clean, spacious, but still very cosy. It has all the kitchen supplies you need, fresh towels, even a washing machine for you to use. I've never said this before about an Airbnb, but I could see myself living here!
From the appartment it's a 10 min walk to the old city centre / bakery / supermarket, etc. Although it's in a crowded part of Naples, you won't have any trouble sleeping here, since the appartment and the building in it's in are very quiet.
We were picked up at the airport by Roberto, who manages Gianluca's appartments. He is very helpfull and communicative. Gave us a lot of nice tips for visiting the city and where to find restaurants, supermarkets, etc. He's offering a return taxi service for 15eu to the airport, unfortunately he was unavailable for our return trip, but nevertheless he booked an official taxi for us (which costs 20eu). I really enjoyed the communications with Roberto and our stay in this appartment.
