All (and I mean ALL) the PHL airport hotels are old, poorly soundproofed, dreary and sad (except the new Marriott). Best HH deal is the Double Tree on Samson St on the Penn campus. Itsa easy 15-20 minute 8-10 dolla cab ride away and is new, clean and quiet. Nice restaurants there and nearby too. Try it, I am certain you will like it.
