The Chili Peppers House is a great option for a short stay in Naples as it has all the basic amenities you'll need. It's also close to the city center and 5 minutes away from the famous pizzeria de Michelle.
Maria is a great host who was very flexible with my check in and out and she provided lots of tips on the area. The only reason why I didn't give it a 5 stars is because I stayed over on a weekend and the street was busy at night (I guess part of the Naples center charm).
Overall I had a great experience and will recommend this place.
