I have to admit, the first email did seem kind of direct and harsh. However, I also understand that this is Vegas, and it’s next to the University, so he is probably trying to keep people from trashing the place and throwing parties. I can certainly appreciate that.
However, when you communicate with Jason, he really is a nice guy, and very accommodating to request. If you respect his place and communicate. You’ll enjoy your stay as much as me and my group did.
