Try the Camaya-an Paradise Beach Resort. I haven't been there, but as a beach resort I would expect rooms at ground floor level. They're just across the river from Bayawan. https://www.camayaan.com/
Checked out the Camaya-an Paradise Beach Resort, looks great (family house sleeps 5 with beds first and second floors). Ready to book but wife came home and said she has to stay with the soccer team and help cook dinner and breakfast so no one to assist me so I can't go and will watch the videos.
