Robert & Juan Carlos were great hosts, and I enjoyed my quick, one-night stay at their place. The house is right by Twin Peaks, and easy to to walk to from the Mission District. Communication was easy, and Juan Carlos was very kind and got me settled in quickly. The room doesn't have a window, but there is an overhead fan that kept it cool during the day and at night. I definitely recommend Robert and Juan Carlos's place if you're looking for a convenient, but quiet place in the city!
