We really loved Sydonie& Raphaels place in Williamsburg. it's the perfect spot to discover Williamsburg and very close to the subway to enjoy the rest of NYC. The appartment was very clean, check in was a breeze and the hosts always responded within hours to our questions.
Unfortunately the upstairs neighbours are very noisy. I assume they have kids and sometimes you think they are plaing in the appartment and not upstairs. We did not mind during the day or in the evening but sometimes they got up around 6am which was not the nicest way to wake up.
