We rented Mango House for 33 days, there were 2 adults and a set of 10 month old twins. This house had more than enough space and would be great for a larger group. Owners Luis and Claudia were very gracious, met us in Merida to escort us to Mango house and were there to answer any questions we had as well as make arrangements (weekly house cleaner, translations, etc). Misael, the property caretaker, was a treat. He would check in every couple of days and had a great time visiting with the twins. His English is almost non existent as is our spanish but we made it work.
Just a heads up, this is not the Cancun Hotel Zone. The house is on a great beach in Chicxulub, a small fishing village. If you want to experience the real Mexico and are not interested in gorging yourself at an all inclusive this is the place for you. We did have a rental vehicle and travelled a fair amount, Luis can provide some recommendations. Being more centrally located than Cancun we were able to visit many more sites (the twins limited the length of our drives each day) and find some gems. Hint: skip Chichen Itza and hit up Uxmal, trust me on this one.
The house was great, location was great, weather was great, definitely recommended. The only issue we had is that some ants found their way into the house and we had to deal with them.
