A perfect place to stay if you want the pros (cheap, safe, opportunities to meet friendly people) of exploring a new city while living in a hostel, without any of the cons.
It was clean, comfortable and well located, just a 5-10 minute walk from an area that's filled with good food and night life but not close enough that you are disturbed by the noise. I would definitely come back and stay at Ernesto's when I have the chance!
