The hostel itself was lovely, I was able to meet some great people in the common room. The place is cleaned daily and nicely furnished. The only issue I encountered during my stay is the checking-in process. There are check-in fees for check-ins earlier than 6pm, which I personally find unfair due to the fact that 6pm is very late in the day. Moreover, if you wish to check-in early, there are no way to enter the building by yourself, as you receive an entry code for the main door that is only activated at 6pm. On my first day, I had to wait over an hour to enter the building, with all my bags outside. When I arrived, nobody was at the reception.
It seems that their check-in system is very messy, even the employees seem very confused about the reservations.
