The location of Mark's place is perfect! There is a Starbucks and grocery store just around the corner. The C line runs just around the corner, which provides access to almost all of Manhattan. Also, Central Park is just a block away.
Mark has a dog which was evident on the couch and bed. Mark most definitely lives in the space as there were leftovers and used towels on the back of the bathroom door. Having two people in the apartment was a challenge when trying to get ready for the day, as the hot water would run out extremely quickly.
Communication with the host is through a secondary service. They seemed to communicate well until the week before travel. I was extremely nervous about being in the city and not being able to get into the apartment.
Overall it was a great place to sleep after a long day of sight seeing.
