I've never used Airbnb before so I wasn't sure what to expect, but I was *very* pleased with Dan's place. It's in a nice location uptown (but up a couple flights of stairs if that's of concern to you), very clean, comfortably decorated, and quiet. Dan is very thoughtful and accommodating, and he's hosted enough to have all the details figured out. (Where do I put the key when I leave? Do I have to wash the dishes? Just leave the air conditioning on or what? That kind of thing.)
The bed deserves special mention. It has that nice medium-firm *super* comfortable thing going on. I slept SO well.
Dan keeps a very clean apartment, and of course he expects your cooperation in that regard.
Finally, the price is very reasonable for Manhattan. Dan's place is an excellent value.
