The front desk is often not attended. It is high risk that people can come in (tailgate) when other customer enter the property though it is locked with passcode. The location is just ok, not too far from the main attraction but you need to walk a bit (about 10min) to get to the nearest tram. The walking path might be a bit dangerous at night. My room has not be cleaned since I checked-in. The WIFI is so slow and intermittent. For EUR130/night, this place is not worth to stay at all.
With only one lock, and free access to anywhere in the hostel, the security is in question, especially while leaving the bag at the open lobby entrance. Big bags are not allowed in the room??? Why? Location is fair, though far from the downtown, but easy access by subway. Poor facilities. Other hostels I have stayed will provide unlimited free internet, but here only 10min and next have to pay. So expensive.
The location is quite isolated and scary when walking at night. The atmosphere is messy, feel like staying at illegal immigrant camp. However, with the passcode doorlock, the security there is really good.
