Keiko and Ilya's place was a great home for us while staying in NYC. The apartment was even more beautiful than on the pictures shown on their page. It's conveniently located, close to the subway, some coffee and dinner spots and a few supermarkets. They answered quickly and very friendly. The kids bedroom (so to speak) was a little hot during the mornings but we slept great whatsoever: we were staying with a family of three (mother + 2 daughters) and we all had our own bed, being a 1p bed and a 1p mattress in the kids room and a kingsize in the master.
Would definitely recommend if you want the explore the city but also come home to a relaxed, aesthetically pleasing and welcoming apartment. :)
