I spent 6 weeks at HackerHomes, both Menlo Park and Mountain View.
The setup is really interesting with lost of smart people in silicon valley to push the envelope.
You'll meet interns at the big companies of the area, startup founders, Stanford students or aspiring ones.
Each home as a caretaker for any eventuality, so you do not depend solely on Vic for day to day things.

Vic also organizes parties every now and then, in my particular experience a birthday party turned into end-of-intern-season.

Vic was also really flexible as my arrangements changed twice during the 6 weeks.

The homes are well setup no keys, just pass codes for doors, all info is written out on whiteboards so you are all set in few minutes.
