I stayed here during my summer internship and it was a nice place to live. First of all, Len is a super-kind person and he has lived in San Francisco for more than 10 years -- I heard many interesting things about SF from him. Secondly, its location is impeccable. It is located in a very safe area, and very close to Safeway and Whole Foods. Even without a car, there is no difficulty in buying groceries or daily necessities. Also, it is located in a central area of SF, so easy to access tourist attractions. Finally, this place has a pretty large desk - sometimes I worked remotely at this place, and it actually provided a convenient working environment too.
