Surya's house is very clean and beautiful. The room is spacious and has everything you need for a nice stay. Surya's house is located about 15mn walking from Coyoacan market. It's 3km far from metro station, but you can catch a bus that pass very often to get to the metro station.
The only thing that for me was a bit annoying was the fact that to enter the condominium you have to call and wait for the house gardian to open the door. I felt uncomfortable every time I had to call them to open the gate, very late at night or early in the morning, even though they were always polite and never complaining. It's the same for cars, whose drivers honked day or night in order to get the gate open, meaning that you can hear the beeps at any time, day or night.
