Location is excellent. Checking in after 2 pm is annoying a bit, I had to leave my stuff but nothing bad happened. Since I did not have any guarantee, I was worried and went back to the hostel at 2 pm to check in. The latter was done fast. Checkout was quick as well.
At the beginning the heater in the room was turned off and I caught cold, then I asked them to turn it on and it was too much.
My take is that the room 7 was a bit smelly.
The staff in general is friendly and ready to help, one of them also suggested me a Spanish breakfast menu to try when I asked her, another answered me a question about the bus ticket, another suggested me a place to buy Mate. :)
