Maria's place is excellent. We were warmly welcomed by her. The communication was excellent and the view is really cool. The apartment is close to many great areas around town and we were in walking distance to many of the main sites and the apartment is a short trip away from the train station. In saying that we didn't have a good experience in Naples at all.
A warning if you're staying in Naples:
When we left the apartment my wife and I were targeted by men on Bikes around the area. We noticed that we were being observed so we left back to the apartment immediately. 100 meters from the apartment I was assaulted from behind as a man attempted to mug me. After wrestling the man off of me he pushed my pregnant wife to the ground and she sustained minor injuries. We have never had an experience like this before with any of the places we have stayed at. If you do stay at this place within this area and I believe within Naples, in general, DO NOT take any jewelry or anything that may look remotely valuable. After the assault, we felt in danger and the next time I left the apartment I was being watched by a man on a bike close by. We left the same day we arrived.
