While the surrounding development seems nearly vacant, the hotel is nice and the service was very good. I spent a couple of night there and had to eat in the hotel. I was pleasantly surprised by the quality of the food and the speed at which it came to the room.
I am sure that it would be nicer if the overall development was active, but i enjoyed the peaceful nature of the hotel.

We stayed here this weekend for a friend's birthday party and had a great time. The hotel has 24-hour room service, which was an amazing surprise. We also took full advantage of the warm indoor pool during our stay as well. The bed was super comfortable (I never wanted to get out of it in the morning) and the rooms were clean but a little dark. My only qualm is that the bar closed awfully early (around midnight /1230) even though there were a ton of us there ordering drinks.

I really don't have much to add to previous reviews. This hotel is clean and quiet and the beds and bedding are just great. At first I resisted staying here, as Princeton was further from our destination than other areas, but the family member I was traveling with is a Starwood Club member and insisted on it. We stayed on the private Club floor and it was great fun.

I used the "Westin Workout" room and it was well equipped and comfortable. Didn't eat in the restaurant or use other amenities. Wifi worked great. Temperature control was easy and pretty quiet (heat). The only that gives away this hotel's age is the elevators - they can be a bit creaky - but that was not an issue for me.

I would certainly stay here again and would recommend it for visits to the Princeton area.

Pluses:
Front desk (Frankie) was very friendly and helpful. It has the quality that you expect from Westin. I wouldn't be surprised if this is the nicest play to stay in the Princeton area.

Minuses:
Only one elevator was working when we arrived. The room was not properly prepared (no shampoo and conditioner, only one bathrobe) - though the front desk called back to make sure we received the missing items.
