We had a pleasant stay at Katherine's and Francois'. When we arrived, the apt was clean. There are a number of supermarkets, shops, cafés and restaurants within walking distance. We also enjoyed occasional runs in Prospect Park. The subway isn't far either - you can easily get into the city center to do some sight-seeing/ shopping etc. Katherine replied to all our questions asap. When we discovered some cockroaches/bugs in the apt towards the end of our stay, she made sure we were provided with effective insect traps immediately.
