Ben's place was awesome, and he was super great host! Although we never met Ben in person, he was extremely proactive about and responsive to questions we had.
We arrived way late into the night (1 am), but Ben still responded swiftly.
The space is super cool. Gorgeous loft, and also great views from the rooftop (access by key), which also has a nice hot tub and pool that you can access whenever. The couch pulls out into a bed, but it was super comfortable to sleep on it directly. Ben provided everything, including beach towels!
The location can be a little sketchy-looking at night (there are always some people on the streets, but they don't really bother you), and there will be some noise (it's downtown after all), but it's very convenient in that the metro is literally right downstairs, and there's a huge underground parking structure (Pershing Square) just one street over. Price was pretty reasonable ($16 a night), and was very clean / safe (as in has security).
Grand Central Market and other local attractions are just a block or two away, and you can see a rooftop bar across the street from the window.
All in all, a really cool place. Thanks Ben!
