Eh - as far as Airport hotels go this one is ok.
Comfy rooms. Decent amenities. Easy access. Nice views from floors 5 and up of the runway with planes taking off and landing - the view from the 6th floor was lush and nice that I left the drapes open the entire time I stayed there.
You can get here straight off your plane by taking the pedestrian walk way from the airport directly into the hotel. It's really nicely done and you get a good scenic view as you walk away from the airport and the major freeway.
Just be careful if you don't have plans to go into the city you might just get stuck indoors for two days!! :( There are taxis to the downtown part of Pittsburgh but it'll cost you a lot. Better just to rent a car and since you are at the airport it is really convenient. The hotel does offer shuttles services to a nearby mall but we were pretty busy with the wedding events to have time to jump on this service. Honestly, I don't enjoy staying at Airport hotels unless they are in the heart of the city - which you rarely find anyway.
I was there for a wedding so my review below is of the Regency Ballroom:
Very spacious and great ballroom staffing! Everyone was so wonderful at the bar and at the tables. But the kitchen staff could have been a lot better at handling the food. The supervisors were pretty rude.
The great hall was massive and accommodated all 200+ guests at the wedding comfortably including the massive dance floor. :) The sound system was great and the DJ looked like he was getting the help and the assistance he needed from the hotel staff too.
Restrooms are nice and clean and close by to the grand hall. Great for the guests! Over all the banquet hall and experience was nice.
