I don't like leaving bad reviews, because of the effect they can have on the livelyhood of families, but there isn't anything else to say about this hotel.
The location is super close to the Tulum Mayan ruins which are amazing. But everything else is a negative.
The hotel staff seem to have a certain fed up, jaded attitude towards hospitality, though not explicitly rude, they are far from accomodating.
On arrival we were prompted to pay cash like a lot of the other negative reviewers here, but it was made very clear on a large poster at reception that no credit card billing occurred, this was fine.
Once in our rooms, after days of hot travel I decided to shower and shave but there was no running water in our room. We asked reception and they told us to wait an hour. We did and then had only dribbles of cold water from the taps.
The air conditioner was very loud and sleeping in the dense heat without it running was a better trade off.
The food was quite strange at the hotel restaurant but I highly recommend the Mexican Restaurant directly over the road.
All in all I would go for this room unless you are paying less than $15USD a night and can weather all of the aforementioned unpleasantries.
