This was my second time in a hostel and it was perfectly fine. Beds were clean, check in was easy. There is a luggage room you can use in case you arrive early. Breakfast is provided and you can even cook for yourself.
The only negative points were: the door to our dorm sometimes didn’t shut properly so one time I left it open on accident and only realized a bit later. Especially during night this is a safety concern. The water tap was super loud and the water pressure was way too high so washing hands made a mess. The door on the 2nd floor is very loud so if someone comes back late at night this wakes up quite some people.
