We have stayed here several times over the past few years, most recently for three nights. Most of the other reviews have covered it:
Great Hospitality (including tea with home made cakes and outstanding breakfast)
Tasteful, comfortable, spotless accommodation
Beautiful water/creek front location
Pippa and Mike sorted everything for us, bookings for meals out (don't miss Marwicks Brasserie) and suggestions for things to do in the occasional rain shower as well as advice on the best walks.
Don't think there can be a better place to stay in Bosham.
