Residence Inn by Marriott Philadelphia Langhorne at 15 Cabot Boulevard East, Langhorne, Pennsylvania.

We stayed here with our two small children. The rooms were clean. The bathtubs didn't hold water, so we had to use cups to stop the drain. The breakfast was an absolute mad-house, quite messy and no one cleaning along the way - so the breakfast area became a mess. The pool...it was absolutely GROSS. There were huge hair balls (visible before we got it) and a film of what looked like Baby Oil on the top. We asked management to clean it, as we stayed there so the kids could also swim. Two hours later and no one cleaned it....eventually they posted a sign the Pool was closed because it was so filthy. Maintenance cleaning would do this place well. Everyone was very friendly and we would go back, if they can get ahead of the mess.
