Stayed here for a month and I thought this was a great choice for an authentic NYC living experience. The UES location is the winner here: very residential, near plenty of amazing restaurants, stores, pharmacies, the Q and 6 subway lines, about ~15 min walk to Central Park, and generally felt safe compared to other areas of Manhattan.
Like another reviewer said, the apartment is a classic Manhattan studio - small, clean, comfortable, looks like the pictures. It faces the back of the building away from the street, so it’s pretty quiet. The amenities provided in the kitchen, bathroom, and closet went well above my expectations, and I was happy I didn’t have to buy anything like toilet paper or cleaning supplies. Was also really nice to have a washer and dryer in the building's basement and a pre-paid card was provided. Was also a great place to work remotely - there is a desk in the living area and I had no problems with the WiFi. Didn’t really use the kitchen other than to make toast and to heat up leftovers, it’s pretty tiny (not uncommon for Manhattan though). Saw no bugs or mice. Check-in/check-out was easy, and Di was quick to respond to questions. Overall, I had a great time and would definitely do a long-stay at one of Inna and Di’s listings again!
