The staff were nice, but we left before our reservation was over due to a number of factors.
The hotel is far enough out of downtown Tulum to not only be inconvenient but also scary to travel to at night. It is far enough down the main road that there are no street lights for a portion of the walk. I would recommend not making this walk alone, just take a taxi instead.
The rooms were noticeably built by hand; there are gaps in the corners of the walls and under the doors that allow in many (large, scary...) bugs. You could hear every move of the upstairs neighbors. The rooms were dark, especially the bathroom which was more creepy than quaint. The showers were nice and hot though, but I felt I needed to wear flip flops while showing. We also discovered that water ran down the walls of our room when the upstairs neighbors showered, which was the last straw that lead to our departure.
