This was my first time staying by myself in a hostel and overall, it was pretty good. I think the experience can be heavily influenced by the people sharing the room, for better or for worse. I had luck and met very nice people.
The installations are a bit old, but clean; the mattresses on the beds might need a replacement, but the sheets are clean.
The personnel are very attentive and friendly.
The location is also convenient, it is near to the city center so you can visit lots of tourist attractions by foot, or there are several bus stops nearby.
I would recommend bringing your own lock, so you don't have to buy one.
