I would technically give this place a 3.5
I'm not the biggest fan of Pittsburg water and I feel like the towels were all strange because of it; from texture to smell. Other than that the beds were comfortable, the king size room was spacious and the gym was above average and very equipped.
The conference center was clean and beautiful.
Service: everyone was really friendly and helpful which I always appreciate the most. It was super odd that the Starbucks and Bill' on site closed in the afternoon on a Saturday.
Location: The Westin feels like it's right in the middle of everything one would need. From very delicious restaurants to entertainment. Close to major historical sites and the water. Definitely go on the river boat tour, it was such a blast.
What I like the most is their eco-friendly options. You can choose to make a few different green choices throughout your stay and that's definitely a plus if you don't mind not having your bed made every morning.
