Stay with Marco was great. It was well furnished and spacious. The hot water was a little tricky, but he states that in the listing and in the welcome note (i believe). It is situated feet to Christmas alley and has tons of food options. The busy square is a 10-15 minute walk. We (two ladies) felt safe in the space with the double lock feature. There will be outside noise, but it is expected for its location. We would stay again with Marco next time we are in Napoli.
