We came across this budget 4 room hotel via owners referral. Though he obviously has a vested interest in renting out a room, he initially drove us (he's a taxi driver as well) to other hotels we were interested in checking out first. Upon seeing other hotels, we settled on Sun Breeze because the room available was clean, comfy, secure, private bath, fan and at a reasonable price.
The host proved to be very helpful in coordinating trips to the Tikal ruins and knowledge of the surrounding areas.
The hotel is located along the lake, away from the 'hustle & bustle' of town, in walking distance to several decent restaurants and along the main road (in case you need to catch bus to 'downtown'; Flores/Santa Elena ~20min)
