Pros
Location: is awesome. Only a few blocks from time square and public transit. A block from Restaurant Row and in Hell's Kitchen, so lots of choices for food and drinks any time of night.

Host: (Grisel) was very gracious and flexible. She wasn't there to check us in because of the time that we arrived, but she had the keys waiting. She was awesome with communication and did what she could to accommodate us. She even bought us a little going away gift :)... She is a sweetheart.

Apartment size: Very Spacious for New York standards. Big Living room with decent sized TV and Decent sized kitchen. You can easily fit 5 people in this space with no problem.

The bed we slept in (last room) was very comfortable and completely silent.

Amenities: The DVD player and cable were great for relaxing after long New York Walks. The WIFI and printer was great to find deals and print tickets for different events.

Cons
Layout: This may be my fault but I did not notice that the "railroad apartment" in the description; but you have to travel to one room to get to the other. There was also an opening between the rooms making privacy very difficult.

Amenities: The Iron was outdated, almost useless (we had to go old school and wet a towel) and we could not find a microwave for the life of us!

Stairs: A minor inconvenience, but the apartment is on the 5th floor. I have never lived in a building without an elevator, but that is why God gave us legs!

Conclusion
DO RENT THIS PLACE OUT! We had a blast for our first time in New York. The biggest issue was the privacy, but that was not a big deal so don't be discouraged. The Pros do outweigh the Cons because the location and the price where awesome. For 2 couples sharing that meant less than a Hundred American Dollars (price split in two) a night for an awesome location.

It is beyond perfect for a family. And extremely do-able for couples. The locals in the area and the building were very nice and we had no trouble getting around.

Tip: download HOPSTOP, a free app for smartphones. It has up to date train info it was all we used. We got in trouble with some closures, this app is great.

FINAL NOTE:
Just ask the host questions if you have concerns. She is quick to answer and pretty flexible.
