Mayfair Library is a community library located at 25 South Audley Street, London. One of my favourate streets due to its mix of uses, architecture and charm.  Despite Mayfair’s reputation for wealth and business, the library serves as a cherished community space, offering not only books but also a variety of events and services for local residents. It alos offers weddings and sits virtually on Mount Street Gardens.
 
Interesting facts...
Mount Street Gardens was actually a burial grounds and I believe contains more benches per area than any other London Park.
