We had an excellent stay at the hostel, and the four days we spent here has been one of the best parts of our trip. We had a room which was recently renovated, and was perfect for us. While there were 5 people in the room some nights (including the two of us), it was split into an upstairs and downstairs sleeping area, giving us excellent privacy for a hostel. Other rooms and areas may differ, but the overall feel was very positive. The hosts we're also incredibly helpful, and gave us all the information we needed on getting to the town from Naples, and also about many of the local walks that are available (get ready for a lot of stairs...). The town is also significantly cheaper for restaraunts, cafes and supermarkets than others closer to the coast, but also has some of the best views of the Amalfi coast, about 2 minutes walk from the hostel.
Exceptional place, and a great town. Highly recommended!
