I stay at Hilton properties pretty much exclusively, and this Hilton in particular is really something special. Beautiful rooms, friendly staff, great room service, with a comfy and upscale vibe without being intimidating or stuffy.
It's early May right now, which means it's allergy season here on the east coast. I booked a "Pure Air" room which has hypo-allergenic bedding, an air purifier in the room, and some other anti-allergy amenities... and it really does make a difference. I need my allergy meds during the day when I'm out and about, but in the evenings when I'm back at the hotel I'm totally fine.
(Full disclosure: the only reason I booked this "Pure Air" room is because it was all they had available. It's possible the other rooms are also sniffle-free.)
ProTip: The hotel is right within the University of Pennsylvania. For anyone hoping to sneak out a UPenn discount on a hotel room, don't bother. Apparently everyone tries to do this... so the only way to get a UPenn rate is to have someone at the University pay with University money, almost like an interdepartmental thing. I'm a contractor for UPenn, and I couldn't get a discount. Bummer.
It's a spendy hotel, but you definitely get what you pay for.
