I travel a lot and can say that Mark's place is the best stay I have ever had. It is suitable both if you are traveling for vacation (close to the Central Park and metro) as well as for work (I worked from apartment, internet connection is very fast). Location is prefect, less then 5 mins from the Central Park, same for the entrance to the metro station. Place was super clean and fresh, flowers delivered by Mark were extremely beautiful. Amenities were exceptional. Mark organized everything in a straight forward way, so that we could easily check in. Check in story is another point to mention: we had to check in too early: way earlier against check in time, but Mark was very flexible to let us in as early as we needed. I highly recommend Mark's place!
