Our stay at Coconut Grove was very lovely. The house is very well prepared in every aspect and has all the comfort you might look for. No A/C but you will survive with opening windows letting the sea breeze in.
We really enjoyed going to the deck infront of the house, doing some snorkeling, fishing or just taking in the views.
It is located next to the airport, which makes it quite fun to sit in the terrace and see the planes comming right next to the cabana through the trees, but a bit less so if you want to have a late morning in bed or an afternoon nap. (flights starts at 8 am and continue till the afternoon )
Another slight downside is that the place doesnt provide you with bikes, you have to rent them, for 15bz per bike/day which we found a little unreasonable considering the price, and that the house is far from the center - not much, 20' walking to the split, but as it gets dark early and we were adviced as a precaution not to walk along the beach, it felt a little unsecure at night.
A suggestion to the owners; due to the increase of seaweed in the sea, a lot of it accumulates in front of the cabin, leading to really bad smells in days without wind. It could be a good thing to have it cleaned up as we saw it being done in front of other places.
But all in all is a terrific place and we enjoyed our stay both in the cabin and in Caye Calker a lot!
