Penny was one of the best host I have ever had the pleasure of meeting. Her apartment is located in a great area, a mere block away from great restaurants. The alcove is just right for one person, doesn't hurt that the bed is amazing comfortable.
The E, M, and the 6 train are close as well.
What I think really made this trip stand out is Penny herself. She was so accommodating of my changing dates and arrival times and once there, she wanted to make you feel right at home. Having chats on her couch with a glass of wine was some of the best times on my trip. I will recommend anyone to come and stay with Penny, I know I will :)
