i stayed there 4 nights and was surprised how nice it was.
A huge comfy bed, nice TV and nice bathroom. Everything is clean and breakfast included, staff is helpful too.

This Hotel has lots of potential but is understaffed and not maintained. Upon entering our
assigned room it was hard to get the lights on since the switches are in the closet. The TV cabinet door would not close and presented an obsticle course.. Carpet needed shampooing and the phone did not work. TV was old analog unit, foozie at best. Asked for another room and the card keys would not work, after more card keys, we discovered this room reaked of smoke so we went back to the first room. During our trips to the front desk we encounted a guy who was on his 4th try with the card keys not working and he was at his witts end. Tried to get water out of pop machine and it was out of stock but kept our money. Desk offered no remedy. On the plus side, the beds were double sheeted and linens were decent.

I stayed here with my family for the Gem and Mineral Show. The hotel is huge, but there were hardly any guests for what should be a busy weekend. We kept taking laps around the hallways trying to figure out how many rooms were occupied, and we think it was probably less than 20. Normally in a large hotel you'll see people hanging out in the lobby, but it was empty.

But despite the eerie quiet, the rooms were nice and large. My parents were traveling with a ton of stuff and it all fit. The location is literally right down the street from the airport. In fact, I accidentally grabbed the wrong bag at the airport, realized it once I'd settled in at the hotel, and we were able to zoom right back and the owner of the bag hadn't even left baggage claim yet.

The one complaint I have is the continental breakfast. They ran out of something every morning. Once it was hot water, so no one could make oatmeal or tea. Then it was coffee. Then it was silverware. For having so few guests, you'd think they would be able to keep the dining room stocked.

Overall, a really nice hotel, good value, and if you're looking for peace and quiet, this is it.

I spent a night at Clarion Airport Hotel, after landing at Tucson airport in the late evening.
Location is very close to the airport, you can even walk there, or take a 5$ cab ride.
I've found the hotel quite different than pictures in their websites, but all in all clean and confortable. Breakfast is included (toast, eggs, sauasages, fruits, cereal, etc).
Staff not incredibly friendly, but not rude as well.
Considering the rate, a very good choice, I would recommend it!
