Great view that holds up to the pictures!
Keep in mind that the apartment is on a hill (hence the great view) and the closest supermarket is about 15 minutes away by foot. Absolutely no problem for us but something to think about if you are older or in a weaker condition.
Andreas is a great host that responds immediately and gave us some really good tips. Unfortunately the owner of the apartment was also in the picture and kind of overbearing. After helping us out with a little problem over WhatsApp she came to the apartment to check again, even though we explicitly told her that we are happy the way it was. She also reminded us three times to leave upon the agreed time - even though we never showed any signs that we would leave late. She changed said time to 10 minutes earlier 1 hour before we had to leave, culminating in the cleaning ladies knocking on our doors 5 minutes before check-out. Obviously these are all little things, but we felt very rushed with absolutely no reason (we left on time as we had always intended).
This should not diminish your view of the flat though. It really is the way it looks on AirBnB - amazing view, very clean and modern. We had a great time in Napoli and can wholeheartedly recommend this apartment!
