Stayed here for a conference that I was attending at the Westin Convention Center and absolutely loved it! The staff was incredible, especially Taylor at the front desk. He remembered my name each time I spoke to him and eventually my room number as well after asking for about 7 extra keys. Unfortunately, the temperature in Pittsburgh was in the single digits, and being from Southern California, none of us wanted to explore the city much but Taylor provided us with several restaurant menus that deliver right to our room, and still offered free tickets to the car show just in case we changed our minds.
The Hampton Inn offers a free breakfast that was probably better than the meals we received at our conference at the Westin, free wifi, free printing (which really came in handy), and 24 hour free coffee (also a life saver). The rooms were spotless and the lobby was very spacious and cozy to hang out in as well.
Also, there were a few times our group needed to meet and go over a few things and the front desk staff opened up the meeting room free of charge for us to use for about 20 minutes each time which was extremely nice of them.
If I ever get a chance to come back to Pittsburgh (hopefully with better weather) I will definitely be staying at the Hampton Inn!
