We didn't meet Sylwia but she responded quickly when I had a question. The apartment was clean and well stocked with supplies. We had everything we needed, except for decent air conditioning. It was in the 90's when we visited NY, and the temperature in the apartment was in the 80's, making it difficult to sleep. There are two other airbnb rooms in this apartment. Our room was okay for the price because it had its own bathroom. The neighborhood itself is alright and seems pretty safe. It's about five blocks from the subway (Path) station.
