I stayed in Mariko's apartment for more than a month and she was always available whenever I needed help. Her apartment was simple, clean and tidy. She even put some fresh pink roses in the vase on the day that I arrived which was a very nice surprise for me.
Since I am not a TV fan, I found everything that I asked for in her flat. The internet connection slowed down from time to time, but overall it is OK. The apartment is a walk-up, so if you have heavy luggages (like me), it might be a problem. However, she was so nice to help me carry my luggages upstairs although she was in a rush. Her apartment is in a very nice neighbourhood, quiet yet close enough to the shops I need. She is a great host and a very nice person so I would definitely choose her if I ever come back to NYC. Thank you!
