Allen's place is perfect for those looking for: 1.) close access to public transportation (right next to the F line—a 45m ride to Manhattan and less for other Brooklyn neighborhoods) and 2.) a place to recharge for the night before doing it all over again the next day.
The apartment is also quite spacious and could accommodate multiple travelers. Additionally, the apartment is located in a safe neighborhood that really feels like a community. (I thoroughly enjoyed walking around the area and simply absorbing it all.)
Finally, note that since this is a basement unit, it tends to be darker than most above-ground apartments, so be careful not to sleep the day away!
