This is exactly what you think it is: An economical option to stay in if you are feeling cheap. I paid about $50 for one night in a "suite" room and despite my negatives below, I think that's still a reasonable price. I actually think that for that price, these things are to be expected.
On the + Side: The gentleman at the front desk for check in was very nice. The property is very lovely and has great spots for reading and water at various locations that guests can use to refill their water bottles. The bed was comfortable, although after I saw the bath tub, I admit I was a little worried about bedbugs. There are about 8-10 off street parking spots, which are easy to use, and that's a plus in this part of Tulum. Walking distance of many restaurants and some shopping.
On the - Side: I was in Suite 2. I was tempted by the "deep bath tub" description for the suite, so it's my fault. But the tub was stained with mildew and I wouldn't sit on that! There was no tub spout, just a shower, which was dripping slightly all night. I got in the next morning to take a shower and the water just dumped down from the rainfall shower head. I felt like I was in my 20s again, living in a garbage apartment in San Diego, except the shower and bathtub there were better. The television wasn't really attached to the wall, the remote had no volume control, and the wifi did not work after 1 hr. One of the mugs was dirty. I should have stuck with the master suite or the swim up suite!
