I think this house is also used by the owner, since it has a touch of personality that I appreciate a lot. It also has all the modern facilities you need and it's own, pool in the back yard. Not big, but big enough and situated in a nice and very private garden.
We stayed two families, three grown ups and five kids, and we had all the space we needed. The bikes were used a lot, Anna Maria Island is perfect for biking. Quite small and without to much (fast) traffic.
The house is in the end of a No-Outlet road, which makes it a quiet oasis just five minutes walk from the beach by the way. Actually we used the pool much more than the beach, hence the sea water is far to hot for refreshing.
I can definitely recommend this house.
