Let's start with the good:
Jason's place is very clean and inviting. You can tell he takes pride in his space and the location is perfect for those who want to save a significant amount of money by adding a very short subway ride to their plans. The bed, as others have pointed out, is ridiculously comfortable and after a day of (probably) walking more than usual, it's even comfier.
Now the bad:
Check-in was a bit of a mess. We were arriving pretty late in the evening and expected that might be an issue, but even though we communicated details of our flight, Uber status, ETA, etc., there was no one there to greet us when we arrived. Thankfully we caught the door as someone was exiting, or we would have spent the 50 minutes it took for someone to arrive outside in the cold, in a neighborhood we didn't know. Communication was typically okay, but when it really counted, I felt very let down. This is my first Airbnb with the "host will greet you" option and I find it pretty less than ideal if the host is not already in the apartment waiting for you. Other experiences have used lockboxes, smartlocks, etc. for a much smoother arrival.
The bad aside, this is a great place to stay. I would likely stay again​ but maybe plan on arriving earlier so that if there's a check-in delay, it wouldn't be past midnight when I could finally get in.
