Karen was a fantastic host. She did so many extra little things that made my stay more enjoyable. Several times she went to the store and would purchase snacks or ask if I wanted anything in particular. She is very knowledgeable of places to eat and little local things close by that I found really helpful. She is very kind and accommodating and her cats are very sweet. The only thing I personally did not like was the lack of air conditioning in the apartment. Karen has several fans set up in the room but I visited during a heat wave in NYC and it was a little difficult to sleep well. I also naturally sleep very hot which likely contributed as well.
