We stayed 6 nights at Barbaras place and we enjoyed it really much and regretted our decision at no time.
First of all the lockable room was spotless. Clean, spacious, modern furniture, big TV, Wi-Fi and AC. The private bathroom has a bathtub, hairdryer and towels were provided by Barbara (it was even possible to change them during the stay).
The neighbourhood is just great. Powers street is quite calm and safe. Just one street or a few blocks away you can find a lot of bars, diners, restaurants, delis, grocerie stores and so on. The offer matched our needs at all. You will get to the L-Train station in under 2 minutes by feet which will get you into Manhatten (Union Square) in 15min. If you are more into biking, a Citibike station is even closer than L-Train. We didn`t used this but it seemed to be a quite convenient way to explore the city.
Last but not least we experienced Barbara and Casey as great hosts. They were friendly and communicative but otherwise let us be as we wanted.
It was a great experience for us, we can highly recommend this place.
