Mackenzie always replied to my messages right away, in a very polite and accurately way - she's an amazing host. Even left us a list of tips of where to eat and shop.
The apartment is comfortable, big enough for 2/3 pax.
The best part is the location, it's right next to the subway, trains and sightseeing bus' stops,but we could walk everywhere, it's close to all the main parts of Manhattan (great location to go shopping too :D less than 5 minutes walking to Marshalls and T.G. Maxx, among other famous stores). It's surrounded by good supermarkets, restaurants, amazing places to have breakfast - all you need is there.
