I stayed with Kells and Dave for three months. They are exactly the kind of hosts you'd hope for: laid back and easygoing with you, but hold themselves to high standards for keeping the place tidy and making sure you have everything you need. On top of that, they're friendly, honest, and interesting guys.
The room is spacious and the apt is beautiful. I ended up really liking the location — early enough on the L train to Manhattan you can squeeze in during rush hour, but close enough to Grand St. and Bushwick so you can easily explore less crowded scenes in Brooklyn.
