Giovanni's place was really really nice. The room was spacious and clean and had everything we needed (it was nice to have our own bathroom and kitchenette).
All the appliances, furniture, sheets and towels etc. seemed to be brand new and so were all in working order. The mood lighting in the bathroom was a nice touch - good for a relaxing hot shower after walking up mount Vesuvius!
We were initially worried about the neighborhood from reading previous reviews however had no problems whatsoever and we always felt safe.
There were lots of cafés, supermarkets and restaurants nearby (we didn't know that most supermarkets and restaurants close on a Sunday evening so just something to be aware of).
Check-in was fine, we were greeted by Giovanni's mother who spoke no English, however Giovanni was available by phone to help with translations!
All in all I would highly recommend this place to anyone looking to stay in Naples.
