This place is really nice, with the big common area, spacious rooms and bathrooms, I think it has been renovated very recently. Each bed has its own power source, light and you can use your own locker to keep your stuff protected. The bathrooms attached to the room are big- with the 3 showers and toilets, really no queue on the morning. You can also use the public bathroom.
Breakfast is rather sweet but lovely: a lot of cakes, croissants, some fruits and yoghurt, tea and coffee, jam, chocolate cream. Great as for the hostel!
The only drawback is the location, outside of Sorrento, but the walk is okay- and takes around 30mins to the city. You can also take a bus for €1,6 (ticket from the driver but have the exact money ready), so not a big deal. I recommend this place.
