Tonatiuh is a great host and was always available to help. The apartment itself was good for my needs and in a very good location. It's a short walk from the metro station and from many restaraunts and coffee shops. It was also very nice to be able to sit on the rooftop area.
The only problem that I had was that the internet was very unreliable for most of my stay. Tonatiuh was very sympathetic to my needs and had a dedicated line installed for the internet in my room. Unfortunately for me the technicians didn't set it up until the last full day of my two-week stay, but hopefully future guests will benefit from the improved connectivity.
