I stayed here for 2.5 months and was so sad to leave! The apartment itself is very spacious and clean, with a large, well equipped kitchen. Even though it's on street level under the main house, western facing windows means there is lovely natural light in the afternoon and evening. There is also reliable wifi -- I worked from home the whole time and never had an issue.
What is truly unbeatable about this place, though, is the location. It is literally steps from the Panhandle, Golden Gate Park and the restaurants/shopping in Haight-Ashbury. Just outside your door, you can catch buses that will take you directly to the Mission or downtown, and you'll be a ~10 minute walk from the N light rail.
Humaira was a wonderful host -- considerate, accommodating and quick to respond. Humaira and the other residents of the house were also always respectful of my privacy, so I felt comfortable leaving the curtains open all the time.
I also have to mention their dog, Cleo, who is incredibly friendly and brightened my day whenever she came to visit.
Overall, I can't recommend this place enough!
