We booked this house for 3 nights and enjoyed staying in the lovely town of Atrani. Staying in Atrani vs. Amalfi has it's benefits and drawbacks, but I will focus on the apartment -- the apartment was reasonably clean but not great, and we were surprised to find that the bathroom had a shower without a door/curtain, so that the entire floor gets wet when showering.
We were horrified though after then first night when we found many small bugs crawling out of and around the drain. We notified the owners and they were quick to respond and nice, but it was also a holiday and they weren't able to get an exterminator until after our stay. They were quite willing to do what they could, but we found the situation unlivable for a vacation and decided to find a different place to stay. The owner offered a refund, and because of their kindness and the difficulty of replacing our reservation, we offered to take one night's refund (having stayed for one night and leaving the remaining two nights). The owner seemed to happily agree, and said when they receive the money from trip advisor they would give us the refund over paypal, but afterward they stopped responding to our messages.
I would like to believe the owner who said that something like this never happened before, and I would say in most circumstances one would be fine renting from them, but in the end the owners showed themselves to lack integrity and you take a risk by staying here.
