The location was the key to this trip. You are walking distance to restaurants, bars, the beach and even Mission Bay. The place itself is a converted garage wit a big open space with a little bedroom area, next to a little dinning area and kitchen. The only other room is the full bathroom. They have a full fridge and anything else you might need in the kitchen to make yourselves at home. There wasn't any coffee like you'd find at a hotel, so bring your own, OR, like we did, find any of one of the many little coffee shops in the walkable area.
We did not use the bikes or surfboards so I can't comment on that. You do (possibly) share a common area with the guests from the main house, so keep that in mind. It wasn't an issue for us since we were spending almost all of our time out of the house.
All in all it was a great experience and just perfect for my wife and I and our little getaway. I would recommend this place to friends, family and anyone looking for a vacation that's close to the hot spots.
