Casper himself wasn't in the apt during our stay, but his friend Artem took care of everything.
The location of the apt is pretty fine. (3 min to 1av (L Train) & about 8 min to 14st Union Square (bunch of trains).
The apt was typically small but enough for 2 people in the room to sleep in.
We had a wonderful stay and all friends of Casper, we have met were super kind and helped us in every situation.
Thank you for offering us your apartment. I would take this apt a second time.
