The enthusiastically pet-friendly Hotel Marlowe, a playful Cambridge property with quality service, an array of free perks, and a "discovery" theme, loves all pets -- and we mean all. It has even hosted a penguin and a sloth. More conventional 4-legged guests can use the dog bowls with food and water outside the entrance, and their owners can order treats for their beloved pals from room service. Pets stay free of charge, and after 5 visits they receive a lunchbox full of goodies. The staff orders extra-special pet treats, such as a pet birthday cakes, from their "preferred dog treat shop" Polka Dog Bakery.
