We were booked into a ground floor room that smelled musty and moldy. We asked to check out another room up on the third floor and it was the same. By this time it was after midnight, we were too tired to argue. So, we decided to stay in the original room. We were planning to stay there two more nights a week later, so we told the woman at the check out desk. She promised we would have a better room when we returned. She was right. The room overlooked the pool and maybe that's the answer. The breezes from the inner courtyard may have something to do with the fresh smell. I'm just guessing, but I'd ask for a room above the ground level that overlooks the pool. We were very pleased with the room. The hotel is very clean, the service is terrific and the food in the restaurant is good. One criticism is that the business center computer (there's only one and you pay to use it) is not connected to a printer.

I recommend that travelers stay in the city of Cancun instead of the Hotel Zone. This is the best way to experience Cancun and the Radisson offers everything you could need (ex. transportation to the beach, a pool, tennis court, close to good restaurants) for a good price.

The hotel is located in the town cancun and not on the hotel zone. It's a good hotel for 1 night after arrival, but that's it. The rooms are ok and the food aswell, but there is not much in the area.

We stayed here for one night on our way back to the UK from Belize. It is within walking distance of the bus station, just, as long as you have wheeled luggage. Took us maybe 15 minutes at an easy pace, otherwise the taxi fare is about US$4. The hotel was actually more upmarket than I was expecting with free wi-fi internet in the room and smart decor throughout and a reasonably sized pool area which we overlooked from our balcony.
Our tariff didn't include breakfast so we walked out and had a great breakfast at a smart cafe packed with locals about 300m. along the street - turn right out of the entrance - and it occupied a corner spot.
There is a small but interesting Mexican market along Ave. Tulum, behind the fire station, where we picked up some souvenirs at good prices without the hassle of haggling.
This was a good place to unwind after a fairly tiring trip and I'd recommend it if a hotel in the downtown area is what you are looking for.
