This is a Philadelphia bed and brekfast booking agency that is not very well known. They have the inventory for various bed and breakfasts and apartments that do not take bookings from the public directly. I have booked through them three times for out of town guests with specific needs and BNB PHILADELPHIA has been great in terms of finding available units for my dates that met the demands of my guests (kitchen, apartments, quiet, etc.). The lady (Mary Ellis) that books over the phone is very sweet. Perhaps because they are not well-known, they were able to find availability for me during a major convention in town had many of the major hotels booked.
