I read a lot of reviews before I stayed here and was pretty nervous before I checked in. Mistake. It is a beautiful hotel in a great location.
The floor I was on must have been newly remodeled within the last 2 months, IF THAT. The carpet was brand new, soft and elegant. The furniture was new, modern and clean, beds (as most Marriotts are) were the comfiest you could sleep on and the Bath and Body Works toiletries are actually extremely pleasant. Front desk staff was busy and checked me in without a single hello- just asked for my name, cc and handed me my keys, no other interaction...odd. BUT, the cleaning staff and room service delivery guy made up for that tenfold. I was coming back to my room yesterday and saw housekeeping and asked if I could have an extra bottle of the orange ginger lotion and she gave me a handful and was extremely friendly...very nice. She was going to my room next, so I left a large tip for her.
I do recommend this hotel to visitors of Pittsburgh, highly.
