Giuseppe's place is fantastic! Exactly what we were looking for on our travels to Naples - central, clean, great value, nice kitchen, big space, and most importantly - air conditioning!!!!
Once you get to Naples you will realize that every night, the squares are filled with locals until around midnight or so, and the square outside Giuseppe's place is no exception. We didn't mind the noise at all but if you are a light sleeper, bring ear plugs!!
The kitchen was clean and well-stocked with all the dishes you would need to cook, as well as coffee and other basic necessities (oil, salt, etc.).
The bedrooms are all loft-style, so again - if you are a light sleeper bring ear plugs. The beds and futon are super comfortable (can sleep 1-2 people on each of these) but the 4th bed is quite hard and uncomfortable - we ended up sleeping on the couch instead.
Giuseppe provided us with a TON of information about where to eat, what to see, etc. He answered all messages promptly and you can tell he wanted us to enjoy his city. The apartment had a cool vibe to it and was decorated perfectly and made us feel at home.
All in all, Giuseppe's is a great place and amazing value!!! Highly, highly recommend the place.
