I stayed at Jeruschka's place for 9 nights and I had a great time! I definitely recommend this place!
Because Jeruschka has long working days I only met her at my last day in NY, but the communication via email and sms was perfect.
Jeruschka is a very nice, helpful and open person.
I also appreciated the fact that she arranged a taxi from and to JFK airport, that took away some trouble.
The other people living in the same building were very nice as well, I had a drink and a nice talk with them.
The room itself has everything you need and the maps and info about the neighbourhood were very useful too!
Three last things which I thought were great: you really have your own space / key, it's only a few minutes walk to the subway and Prospect Park is close as well and it's beautiful! Especially to run in the morning.
Jeruschka, thanks again!
