I had booked a King bed directly at the hotel chain's website, but when we checked in, two bellhops accompanied us to our room - with twin beds! Back we went to the front desk, where they said they had no King available. After a 15-minute wait, they "found" one, but it "wasn't ready." We had to leave our luggage in the baggage check, so that we could catch the hotel's last shuttle into town. Yes, the hotel does provide something of a shuttle, but it makes only one stop, at the Alhondiga, which is at the very beginning of the downtown area. It also runs only once an hour, and try taking it back! For most purposes, it might as well not exist.
The hotel is, however, conveniently located very close to the Central Camionera, so if you're busing it to Guanajuato and don't have a lot of luggage, you can walk there.
After spending the afternoon and evening in town, we took a cab back to the hotel to claim our room, only to find that the air conditioner wasn't working. Back downstairs again. New room. A/C worked but the room safe didn't, and the desk was dirty, with crumbs and spill marks. The bed was medium-hard, but bearable, and the bathroom was quite large, with good lighting.
After we worked out the initial problems and settled into our final room, everything was fine. The included breakfast was quite nice.
The hotel has a restaurant, Casa Valadez. It's not attached, but on the same property. We had dinner there one night, and we were pleasantly surprised to find that it had excellent food, even if the service was a little strange - the waiter was a complete space cadet. He would correctly repeat everything I said to him, and then bring the wrong thing. And I was speaking his language!
All in all, this Holiday Inn is a decent place to stay, once any initial problems are addressed.
