This place is truly a gem. Not only is it a comfortable space with a great bed and nicely decorated, it's location is as good as it gets when it comes to Brooklyn. It's close to the subway (a lifesaver in NYC) and at the heart of a great neighborhood, with stores, restaurants, bodegas, cafés, services, etc. You can also take the bus from here to downtown Brooklyn and do some shopping and dining, while visiting some iconic art spaces and parks.
Do yourself a favor and just come and stay with Frances and see Brooklyn, and stop by Manhattan too if you have time ;)
