This is a pretty basic guesthouse, but they do not overcharge you for the location like the rest of the guesthouses on the pier. there is no hot water and the rooms are simple but adequate. A little cupboard to put your stuff in would be nice though. A hot shower would also be a major improvement. Beds are hard, but OK, it's also a pretty quiet place. The family that runs the guesthouse is typically Thai laidback and very helpful. The view from the private little pier at the end of the guesthouse is excellent and I ended many evenings just sitting there, being happy.
In Bang Bao it's best to rent a scooter if you want to go to the beach.
