The place is superb, clean and cosy and Karen is a fantastic host. The place is a short walk to the Roosevelt Avenue subway stop and in a very diverse neighbourhood. I can't stress enough how good of a host Karen was, she even provided us with a folder full of information, local hints tips and guidance and was really easy to get in touch with and was quick to sort out any issues we had.
The only issue we did have was the flat being on the 2nd floor, the heat in the building all rises to that flat and it can get super hot at night, for our stay the night time temperature was around 82 degF each night and the air con is quite loud to sleep with on cooling mode. I'm sure this problem wouldn't arise if it wasnt really hot during the stay.
Overall, our stay with Karen in Queens was great and we would highly recommend staying with her!
