Had a really fantastic stay for a week in May with Kai and Bev. Great hosts, offered helpful advice for what to see and do and the bikes were awesome - just a short cruise down to the beach and the Bay Area is right on your doorstep which has lots of cycling paths. We were a 3 and had plenty of room - only thing to note would be that the bathroom is in the bedroom so you'll need to wander through the bedroom to access the toilet if you need to go in the middle of the night.
Can't recommend highly enough, thanks Kai and Bev!
