I can't recommend this hostel enough.
Staff are warm, friendly and ultra helpful.
I arrived at 11:45pm on a sunday, I received a warm welcome, offered a glass of water, check in with minimal fuss, given lots of info about the city and also invited out for a quick drink.
I've stayed at a lot of hostel in my 7 months of traveling and this is one of the nicest. Rooms were clean at all times, big lockers to put my stuff in, comfortable beds and just a general good vibe.
