We stayed in a private room, which was nice. The place was clean and in an impressive building. Being in our upper 40s, we were somewhat older than most of not all folks here, but didn't feel out of place!
There is a nice rooftop bar serving a decent range of drinks after 7pm. They also do food up there, although don't expect it to look like the photos on the walls in the main courtyard room downstairs. It comes served in eco unfriendly plastic, and certainly isn't as gourmet! There is a dj there each Friday evening.
The location is OK. It's around 25 minutes walk in the heat with a loaded bag or 20 without from Sorrento. Or 5 minutes from Sant Agnello train station, although the trains from Sorrento aren't the most reliable. There are a number of local restaurants close by. For us, the slight inconvenience of being further from the centre of Sorrento was not a problem and we'll worry the lower price of the room.
Several aspects were not eco-friendly. For example, the soap dispensers in the bathroom were empty and soap provided in individual plastic packets, the tiny amount in each shampoo sachet making the amount of plastic packaging even worse (Covid can't be the reason for this failure to use the dispensers, given the way breakfast was served and lack of other measures across the hostel) while the aircon could have been replaced by less energy inefficient fans.
