Debbie's beach house is super nice and is in a great location - quiet, yet close enough to town for most. In your immediate area, try yoga at Ak'bol in the mornings (9AM) they also have great breakfast. Aji's is within walking distance for a nice dinner and they have a little market (called LuLu's) that will have all of your staples. Lazy Croc is open on Friday through Sunday for the best BBQ anywhere.

Have a wonderful time!
