We rented this home in late February/early March, 2014. There were four adults and one infant child. The home is in a wonderful location. You are a 5 minute walk to Half Moon Bay and a 5-10 minute walk to Akumal Bay. It is easy to get around and the town itself has a smaller grocery store (you can go to tulum or playa to load up if needed), several restaurants and bars.
The home itself was very lovely. The pool is on the ocean side, which we loved. A lot of homes in this area have the pool on one side, and the ocean on the other. We enjoyed the ocean views while hanging by the pool.
The security on site was great and the housekeeper did a wonderful job. The housekeeper will cook for you (two meals are included in a week stay) and the food she prepared was really good. The a/c worked great and the beds were very comfortable.
My only complaint is we had WIFI issues about 4 of the 7 days were there. Sounds like this was out of the hands of the owners, and was more of a provider issue. Also, there are ants everywhere, but it sounds like this is a problem everywhere in the area, not an issue specific to nicte-ha. Just prepare yourself :)
I would highly recommend checking this property out if you are considering a rental in Akumal.
