Mark was very responsive on all of his text messages and directions to his home. He is a hard worker and is very busy with his music business. The room that was offered was in the third floor of his home. The area was gated and was very close to the highway access. He also let me use his laundry facilities before I left.
Only improvement I would suggest would be that the host shouldn't schedule his work during the middle of the day while guest are using space in his home.
I would recommend this AirBnB to Vegas lovers. He is a nice host.
