I was very well received. While I was supposed to check-in around 6:00pm, Carlos kindly suggested that I leave my luggage in the appartment so that I could enjoy my first day in New York. It was really appreciated.
The appartment I was supposed to stay had a toilet issue, so that I was switched to another Carlos' property in the same building, with a small terrace, which was a sort of upgrade ! However, the appartment was really conformed to what I expected.
