We had a wonderful time in New York at Katarina's place for 5 days from New Years Eve!
The rooftop terrace was perfect for a bottle of bubbly at midnight!
There are dozens of restaurants, bars and brunch spots only a few blocks away, quite a boho vibe. It's also really close (3-4 mins walk) to a subway stop with trains towards uptown or downtown Manhattan.

We didn't meet Katarina but she was very helpful with suggestions about what to do nearby. We were allowed to leave our bags in the apartment the day we left as well, until we needed to leave for the flight.

The apartment is a lovely little clean modern studio apartment, perfect for singles / couples having a city break. The bath/shower are great too. The only very slight downsides are that the sunlight comes in through the huge windows and the curtains in the mornings, but it helps you get up and out early! Also there isn't a taller table to sit down to eat at easily but there are so many places nearby to go it's not a big issue. We would definitely recommend this apartment.
