First of all: Alessandro is the nicest person ever! He is always approachable, responds immediately to your questions and does everything humanly possible to make your stay with him as pleasant as possible. We even got fresh coffee on our last morning :).
Check in and check out was very easy and quite flexible and communicating in English smooth (even if he claims his English is not so good ;) ).
The apartment is exactly as shown in the pictures: the kitchen and bedrooms were pretty new with amazing facilities to cook and eat. More than enough space for 4 people staying over and the air cons (which were brand new, working perfectly quiet and smoothly) were a much appreciated feature after 1.5 weeks in Italy’s summer heat without any cool air at night! The balcony was spacious, offered a clothes line to dry your clothes and had a fantastic view to volcano Vesuvio.
The apartment is located on a little hill (Naples is completely hilly anyway), so be aware that the way up or down to the city center is rather steep. It is still located quite strategically, you will only need 20 mins by foot to the University area and old town part, approx. 30-35 mins to the harbour and roughly 20 mins to the main shopping streets and royal palace.
We did not have any problems walking at all, but it was quite adventurous with the car since the street up to the apartment is small, steep and narrow :D.
You will not find any tourists in this neighbourhood which we totally liked. We still felt really safe.
Ask Alessandro for any tipps and hints in regards to restaurants/Pizzerias or places to visit.
I can wholeheartedly recommend Alessandro’s apartment and we will be back the next time we are in Naples!
