What's most important for a person visiting New York, Yuichi's place is very well localized. Close to a few subway stations (F,G and Q), that can take you to different parts of Manhattan or Brooklyn within 30 minutes. Also close to restaurants; grocery store is accross the street; Prospect Park with a ton of free events is few blocks away. Plus it is pretty safe, current Mayor of the City of New York lives two blocks ahead and goes to a gym just accross the street.
I higly recomend this place for single travelers.
PS. Yuichi has a nice, calm dog.
