Our stay at the Box hotel was okay. We were attending a wedding nearby, so the location was good for us, but overall it's not the best location in Brooklyn. A bit isolated and in a dingy part of town.
The room was nicely decorated but lacking some details: no place to put your luggage, single ply & super cheap toilet paper, no bathroom amenities beyond soap and shampoo/conditioner.
Staff was really nice and helpful. Some of downsides: our room was very bright starting at 6:30am. The curtains do very little to keep the light out. On top of that, you can hear so many things from the hallways: guest's conversation, slamming doors, the loud elevator chime, etc. I highly recommend traveling with an eye mask and ear plugs to get a better sleep.
Overall, a good stay but I'm unlikely to rebook.
