No problems
A fine place to stay. Downtown Coyoacan is about 5-7 blocks away. It takes about 10 minutes to walk. I was only there one night. Breakfast is served in the morning from 8a to 10a, but I did not eat breakfast. There is internet access for 10 pesos...1usd an hour.
I stayed in a shared room. There were a total of 6 beds...3 bunk beds. However, I was the only person in the room, so it was nice. There was a private bathroom for the room that had a toilet, 2 sinks, a shower, and even LIQUID HAND SOAP! :)
The hostel does not look like a hostel from the outside and there is no real sign to tell you it is a hostel. You just have to go by the address. There is a buzzer and you have to buzz to be let in.
If you are staying in Coyoacan, it is the only hostel I know of, and it is by far a great value.
