Atlantic Ave, the northern border of Prospect and Crown Heights, has a couple of chain hotels, and home-sharing websites will reveal numerous private rooms for rent in these areas. But probably the nicest options are the appealing B&Bs and guesthouses tucked into historic row houses and freestanding Victorian houses on leafy side streets. There are some especially nice ones in the tranquil neighborhoods of Prospect Lefferts Gardens, immediately east of Prospect Park, and Ditmas Park, just a few subway stops to the south.
