Check-in process was smooth, resulting in a code to access the front door and the dorm door. I didn't have a towel so I rented one for 3 euros.
The dorm rooms have triple bunk beds. the top bunks are an effort to get in and out of. Each bunk has a curtain for privacy and a reading lamp with a USB port for phone charging. Each bunk has a locker but no lock so bring your own padlock if you're worried about theft.
The bathrooms are too few and too small so when you can get into one it's usually very damp. The showers work decently though. The kitchen seems well appointed but I didn't use it much.
Location wise the building is about a 30 minute walk from the main tourist areas, but you can hop on a scooter to get down there faster. There are a few cafes and bars nearby and I nice park at the end of the street.
