I have stayed there for the location close to the bus station. The facilities are basic, but room was clean. The only problem I had was with the shower. No hot water. But I can not complain much, for the price I paid. Overall is a good budget place to stay, if only for one night.

We stayed one night at Hotel Alux in February. We picked this hotel because of its close proximity to the bus station. It was a great bargain, only about $40 Canadian a night, though it is definitely a 'no frills' sort of place, it was fine for the short time we stayed there. The room was a good size, and was clean. It is a noisy area with lots of traffic, but both my friend and I slept well. The staff was friendly, there was a computer for public use in the lobby ,and purified water available on each floor for refilling water bottles.

I would stay here again if I were ever in Cancun....

We were finishing travels through the Yucatan peninsula and just wanted someplace decent and convenient for the last two nights. That gave us one day to see Cancun which was more than enough for us. The Alux is only a block away from the main bus station which made it easy to get to the hotel and easy to get the bus the last morning to get to the airport and also easy to catch the bus that went to the ritzy hotel zone for our last day look around at how other folks enjoy vacations.
The Alux was clean enough and comfort was OK. The bed was good. Everything in the bathroom worked. They had clean towels for our second night and made the bed up. It would have been nice to have a real window in the room (I did notice when walking around that the rooms with two beds might have had a window) and the lack of that made it feel a bit confining. Our room only had two narrow slits to see through had we been two meters tall (6'7"). But with only the one bed in the room it was cheaper. I think we paid 350 pesos a night which was under $30. Two beds would have made the price about $5 more a night. The room also had a tv so we watched a few Mexican music videos.
They also had breakfast but it was perhaps the smallest breakfast possible. It included weak orange drink, a basket of small rolls that had no flavor, and very weak coffee. At least they offered pats of butter and jam. There was a very nice large grocery store about two blocks away so we supplemented our breakfast with some yogurt and fruit.
The lobby was very small but there was one computer for guests. I worked one of our two days there.
After we checked in our first afternoon we had a good walk around the "downtown" of Cancun. There were many other inexpensive looking hotels and hostels in the area. Perhaps there were others that were better or cheaper. The Alux was OK and suited our needs.

For a mere 410 pesos ($20 each for a 2-double bed room), Hotel Alux was an amazing deal. We booked it because it is one block from the bus station and we had to be on a 4:30 a.m. shuttle to the airport the next morning.

Our room (#408) at Hotel Alux was basic but was very clean, had a great bathroom, was air-conditioned and, while all of the other budget hotels in the area had doubled their prices for Christmas, was worth every peso.

Yes, it's in downtown Cancun so it's not silent and it is definitely no-frills for those expecting anything more than a place to wash up and rest their heads.

But for the budget-conscious traveler who won't be spending much time in their room, but maybe doing daytrips in the area (again, that hub-bus-station is around the corner), this would be a great option for an entire stay – the local bus to the beaches is 65 pesos. I would stay here again.

My only warning would be that for those with mobility issues, the hotel has stairs only and our room was on the 4th floor.
