Everything's fine!
The apartment is located in a relatively quiet street in Williamsburg, not far from cool shops, great restaurants and nice coffee bars in the middle of Brownstone houses. The L-Train, which runs along 14th Street and already has the next stop in Manhattan, is about 6 minutes walk away (Bedford Avenue). The station Marcy Avenue of the JMZ train is about 9 minutes on foot away, this is a great way to get to Lower Manhattan.
We found the apartment spotlessly clean, the bedroom is relatively small, but the private bathroom is even bigger. The bedroom and bathroom are on the ground floor, as are the living room and kitchen, which we shared with Jenn, our great host. Jenn herself lives in the basement, we have (unfortunately) seen her relatively rarely. She is a very nice, helpful, discreet and circumspect person.
Check in and communication were very fast and uncomplicated.
We can warmly recommend both the apartment and Jenn and would come back at any time. THANKS
