I am a fan of this hotel. I've stayed here many times while visiting Pittsburgh and family for holidays and non-holidays. The rooms are big and and usually very clean (never any weird smells like some have repored). I like that they are green and that you need to put your key in a slot to keep the lights on/turn off lights automatically when you leave. The staff are always really nice and have even upgraded me in the past. I usually get my room via Priceline and they are generally the best deal in town for a nice place to stay with a view. (I think the availability of this hotel on Priceline and Hotwire has nothing to do with the quality of the hotel, just quantity. This is a convention hotel and when there isn't a convention going on, it really seems empty...especially on a holiday. During those times it is almost as if you have the place to yourself.)
Quick tip: Park in the huge garage/bus terminal 1-block behind the hotel. Much cheaper than valet parking and inexpensive for downtown parking.
Quick tip 2: A modest tip goes a long way for better housekeeping service. If you want some extra coffee/tea, extra shampoo, extra towels, etc...leave a tip. I even got a nice "thank you" on the notepad.
Quick tip 3: Try the bar called "Tonic" across the street. Good drinks/appetizers.
