All the BAD aspects of the above negative reviews are entirely true, and more.
The shower was completely ludicrous: water went all over the floor as soon as the shower was turned on, the shower head was pitifully outdated and generally malfunctioning The entire area behind the bathroom door was covered in short curly hairs (if you know what I mean), which were there for the entire time (who is cleaning this place?).
We stayed in 2 different rooms over 4 nights and both were as bad as the other. The mattresses had huge craters in them and the springs were unwelcomely lodged directly into our backs all night. The first night we were in a room with a double bed (we are a couple), but for the next 3 nights we were in bunk beds in a private room!! Who ever heard of a couple sleeping in bunks, hostel or not!
The card reader for the lifts in the foyer was seriously malfunctioning - the staff were obviously so used to seeing large crowds of people gathering outside the non-working lifts that they didn't once offer to help anyone work the card reader. I understand that the reception staff can't be running out from behind the desk every 2 minutes to help people with the lift, but if they just fixed/replaced the card reader, this wouldn't happen in the first place. (I notice at least one other review mentions this too...)
Breakfast was average - I advise you to avoid the juice on offer, unless you greatly enjoy the flavour of Vitamin C tablets, which is what all 3 flavours of juice tasted like.
The kitchen was grossly understocked - the owners need to pop down to Ikea and treat themselves to a few pots, pans utensils and cups. Hardly anything to cook with.
We couldn't wait to leave, and would never ever return - not even if it was free. That's another point - I thought the prices were a bit steep - then I arrived and saw the place! Much too expensive for what is on offer. They shouldn't be allowed to charge through the roof just because of their central location. Keep in mind I'm not comparing this to a hotel, only other hostels and general human decency and minimal conditions of existence. Disgusting.
