I took my 15-yr old daughter and her best friend to NYC for a weekend for her birthday. We have been to NYC several times and we always stay at a different AirBnB to get a feel for different parts of the city.
Jelen's place is very clean, and laid out well for visitors. Plenty of floor space for your suitcase/bags, the mattresses are comfortable and the kitchen is equipped for coffee/breakfast. She made it extra special for us by placing a Happy Birthday banner and balloons in the place when we showed up!
For anyone that is new to NYC, keep in mind that most apartments are walk-ups. My daughter's best friend had to carry her HUGE suitcase up to the 3rd floor, so keep this in mind when you pack. Pack light :)
The front 2 bedrooms are above the street, so there will be noise from the road at night. If you are a light sleeper, take the back bedroom (with the bunk beds). The beds are comfortable, but the pillows are a little flat. We enjoyed the location and there is plenty of options for restaurants and convenience shops to buy water/milk, etc.
We would highly recommend this to anyone visiting Brooklyn!
