I have been having a look around as well and like the look of the following that are supposedly guest-friendly...
Lamai Inn + Lamai Hotel
www.phuketdir.com/lamaiinn/index.htm
Expat Hotel
www.expathotel.com/
I have also heard that the The Cadillac, Swiss Villa, Valhalla and Orchid are all guest friendly as well, but haven't found out much info about them.
If I find anything more out, I will post it here later.
Good luck
