Although Ana was not there, she organized everything prior to our arrival! Abraham was the responsible for our reception and he was great, giving a lot of advices and helping in any issues we had. The 10 days we stayed at Maria's apartment were fantastic! Everything was like in the description. Clean and with a great location: near 2 subway stations, the museum of natural history and the central park. It's perfect for 2 people, who want a quiet and nice place in this great city! I recommend this apartment to my friends and everyone who is asking where we stayed :)
And if I will be in NYC again, I would definitely rent Maria's apartment again!

TIP 1: There is a Shake Shack on the Columbus Avenue with W 77th St, they have great hamburgers!
TIP 2: If you are arriving late and every restaurant is closed, there is a bakery that is opened 24h in Broadway with W 78th St. You can find great pizzas in there.

Thank you Ana and Abraham we had a great time!
