I've stayed at this hotel several times and each time was through a Priceline purchase. When I am booking for this area of Pittsburgh I specifically look for 2 things which are free parking and free internet. Of course hotels have different prices at different times based on demand and such but every time I ended up with this hotel I was very please at both the price and the overall facility.
This hotel is very close to Robinson, the Summit etc which I do most of my big box shopping during trips to PA so being close to the highway and close to the places I visit is a big plus. There's also lots of places to eat nearby as well so you have both the shopping and some meals covered off too.
The hotel is spacious, has quick elevators, and plenty of parking. Even on the busiest of times this hotel always has parking which is also free so that is a huge bonus compared to staying in the city. Since Pittsburgh isn't that big of a city staying in this part of town makes sense for us sometimes. The Marriott overall is a great location and for the times we went, a very great value. If I had it my way whenever I go for a hotel via Priceline or Hotwire I'd almost hope I get this one each time.
The internet works very well in this hotel as well.
