The location was perfect, close to Columbia University where I was visiting and an historical area with amazing architecture and beautiful parks, Morningside Park across the street and Central park within walking distance. Subways (C, B and 1) , markets, stores and restaurants were all within walking distance, I recommend Bluejeens on Frederick Douglas Blvd and The Hungarian Pastry shop on Amsterdam.
The apartment is very comfortable and clean and Mie was very helpful and accommodating. There is ample equipment should you need to cook and laundry facilities downstairs. Mie's apartment is large and airy with wooden floors and working AC (very important on a humid New York day).
I was on a working visit so being on the ground floor meant a lot of traffic noise outside at night, that combined with an upstairs noisy neighbor led to a lack of sleep...not ideal when you have to go to meetings in the morning. The noise was the only negative, once I let Mie know, the noise level was reduced from upstairs. Otherwise this is a really lovely apartment and location so I highly recommend it.
