I did not met Nick in person, I only talked to him by messages and mails. He was very nice and always answered to my questions. He also sent a few messages during my stay of two weeks to see if everything was alright.

The apartment is well located and extremely close to the subway, which was very convenient to go anywhere, especially to downtown Manhattan. The area is surrounded by groceries, fast-food restaurants, shops... It seemed a safe area to me.
My room was fine, clean, and in accordance with expectations. However, I found the apartment quite messy... The kitchen and living room could have been tidier and cleaner. But believe me, it was okay, I was not disgusted by anything. Also, I had to buy some base products, such as paper towels... I think there should have been some.
The bathroom I used was not bad, with a large shower cabin. But again, it could have been cleaner. Moreover, the apartment is dark. You have to turn on the lights at almost any time of the day, or you don't see anything.

I enjoyed my stay though, as the apartment. Despite those few flaws, it was big, well located and I was at ease. I was alone in the apartment for a week, then some roommates came and were all nice.
