A fellow guest told me he was offered a 50% discount to write a positive review of the hostel. I was offered no such discount myself, so I will say what I will. The hostel was very clean, the staff was responsive, and the wi-fi was a great convenience. Some of the guests were disturbed by the proprietor's fondness for taking showers with the bathroom door open, his habit of shouting out the names of his employees ad nauseam, and his tendency to wander around the premises clad only in extremely tiny underwear, but perhaps these were simply misunderstood tokens of Ukrainian hospitality.
(In truth, I have it on good authority that this is the best hostel in Kiev, so be sure to consider it if you find yourself in that city.)
