The Inn at Penn is a Hilton Hotel, so it has the amazing sheets (for starters). Though large and imposing in inner decor, it also manages to be warm. Be sure to check out the couches by the fireplace in the library (there's also a bartender on duty in there in the evenings!). The attached restaurant is a little overly pricey, but there a lots of good restaurants in the area surrounding the hotel and the Penn campus. The location of this hotel simply can't be beat if you're in the area to visit Penn!
