Polina's apartment was exactly as described, and a perfect fit for my group of 4, including my baby. It could comfortably sleep more.
The apartment is super conveniently located to Brooklyn Museum, subways, and restaurants, and we all felt very safe.
Polina stocked everything you could need - plenty of towels, linens, hair dryer, etc. She was very accommodating and communicative throughout our stay. The kitchen was great for cooking, and the washer/dryer came in handy.
I really can't say enough good things about Polina's! I would love to book it again next time we come to New York, and hopefully take advantage of warmer weather!
