Jeff's place is in a perfect location and basically a large efficiency hotel room in the heart of Union Square. Check in was super easy, it was a quick walk from the Powell Street BART stop and close to everything that SF has to offer. It also was super reasonable priced, over $100 cheaper per night than any other decent hotel I could find in the neighborhood. Check-in is easy (just like a standard hotel) and the room was really spacious and comfortable with all the amenities that you expect. I did not eat at Zinga in the hotel, but it seemed lively every night.
