Loved our stay, it's roomie, clean and a PERFECT location for walking from the beach and Belmont Pier. it's about a $20 Uber to the Gaslamp quarter and other downtown activity.
Communication from the hosts was always amazing!
If you aren't just completely disrespectful house guests and clean yourself off and/or sweep as much sand as possible the sand is really a nonissue.
I wish this unit had some direct views of the beach, windows, or a patio, and it was a little pricey, but overall it was a great place for a family/friend vacation. I would absolutely stay here again!
