My boyfriend and I visted NYC in October of this year and stayed in Carlo's apartment in midtown (located on E54th street and 2nd Avenue). The location was perfect and there was no noise at night , it felt completely safe. It was a 5 minute walk to lexingtown avenue subway and a 10 minute walk to 5th avenue. The subway line at lexington avenue was really good in that you could be anywhere you want in the city in a very short space of time so I would consider this a very central area and perfect for both the NYC sightseeer and shopper (Bloomingdales was about a 10 minute walk from the apartment) without the noise.If. The apartment was clean and there was plently of clean linen. We had some intial issues with the wifi but the service company were very responsive and had it resolved very quickly for us.
Before our visit, Carlos was always very responsive to any queries and clarifications we had. We availed of the car service provided by Carlo's company also and there were no issues with this either and the cost was very reasonable from JFK direct to the apartment.

Really we have nothing bad to say about our stay in carlos's apt. As mentioned, I would consider this a very central area and perfect for both the NYC sightseeer and shopper (Bloomingdales was about a 10 minute walk from the apartment) without the noise. we would have no issue with returning an staying here again.
