Marcus is a wonderful host, with a modern, inviting spot in a terrific neighborhood (definitely follow his advice to go to Floriole Cafe & Bakery).
His is a unique home, open and roomy, yet with bedrooms that offer privacy. Others have mentioned that the L Train's nearby noise — and my guess is that the excellent value of this home is in part because of the train. If you're a light sleeper it may pose a problem, but the white noise machine should be all a moderate or heavy sleeper needs to get some rest.
