The apartment is very, very big. 3 levels for habitat and a 4th for terrace. It could get a little noisy if you did have 15 guests. Like most dwellings in Mexico nothing is sound proof - any bedroom, even on the floor below, would hear chatter in the kitchen upstairs. It is a private place. The terrace is very nice. The bedrooms all have ample space and pretty sizable bathrooms. Cotton sheets are a plus. No A/C, but there are fans and heaters. The host goes the extra mile for checkin & checkout as well as other communications. The keys, all 4 - for the 4 doors, were placed in order on the key ring. Something I would do to organize the order in which to use them. I think the only thing I felt was odd was there was not much toilet paper - 1 or 2 rolls per bathroom for 3 nights. I think this is something that should just be unlimited for guests. There is filtered water @ the kitchen which I like for reusing bottles! Over-all would book again. Great neighborhood location, apartment is overlooks the trees' canopy.
