Hostel Buenos Aires

1) One member of the staff (I presume the owner, otherwise I don't understand why) tried to overcharge us. He wanted to charge us a 10% more for using a debit card, I asked him why as there was no mentioned of that in booking, and he said "he didn't know why" and provided no further clarity on the matter, I assumed then that it was some Argentinean legislation. To my surprise, when I googled it I found in an official Argentinean website that it is forbidden for businesses to add any extra charges to customers for using debit or credit cards. 2) Our room was an absolute disaster. There was a leak in the radiator (there was a little glass jar by the radiator pipe and a towel under the jar, and every morning when we woke up we had to empty the jar). There was also a leak in the toilet, which made the floor constantly wet and very slippery. 3) The shower was really unreliable. Water would come and go as you were showering. I spent 4 nights there and I could not wash my hair because I just could not do it with that water. 4) WiFi connection was very slow. 5) Sound proofing was non-existent. We could hear EVERYTHING that happened in surrounding rooms. One one occasion we overheard how the same member of the staff tried to scam another couple. 6) They have a kitchen for guests, that is true. But the kitchen is almost empty, there were very few dishes, knives, forks, etc. Defefinetely not enough for all (or even half of) the guests in the hostel.
