Mark's place is in a very nice part of NYC and was very spacious and light for a basement apartment, although that meant it took at least 45 minutes to get into the centre by public transport. Once we got the hang of it, it was pretty straightforward to get, the bus stop about 2 minutes walk and then the train station (M Line) 10 minutes on the bus (or walk all the way in ~ 20 minutes). Mark was friendly and helpful during our stay, even offering to take us to the airport at 6am on departure day!
