We enjoyed our stay in Marea's apartment (2 couples and 1 single). The apartment was clean and tidy at our arrival, and Marea did her best to make us confortable on our stay there. The comunication with her was perfect before and during the stay. In addition the apartment is really well localizated in the center Manhattan so that we never took more than 20 minutes for coming back after a nonstop tourist day. Marea has ready a good book with information of restaurants, tourist information, etc about NYC wich can help to fill the gaps of your planning in case you have one or even to make a plan if you have not any.
We made the 6 days trip during the first days of November, and the weather was already cold but heating worked very well.
I can recommend this apartment as a good operation base for a trip to NYC.
