We attended a family wedding in Pittsburgh, and our family had several rooms at this hotel. All of the rooms were in terrible state, stains on carpets, cupboards full of dust that had not been cleaned in months. Stains on room doors, bathroom door frames were full of mould - as were some of the bath tub edges. The furniture in the bedrooms and bathroom was so old, it was full of scratches and in general very poor condition. The rooms were dark and dull.
The beds were not particularly comfortable.
To top it off, during our 5 day stay, we asked twice for the bedsheets to be changed and were told it would be done, once we complained it had not been done - the reception staff simply say that Housekeeping finish at 5pm and nothing could be done. Overall the cleanliness in this hotel is very severely lacking.
The breakfast area was poorly managed, and not cleaned during breakfast hours. Generally, there were crumbs all round the bread area and toaster. Very poor standards for a Hilton property.
I would avoid staying at this property.
