I stayed at Alice's place for 10 days and overall it was a great choice. Even though I didn't met the host personally, Brian, a co-host, was fast to answer all my questions and I really appreciated the fact I could let my suitcase on the day of my departure for a few hours after the check-out time.
The neighborhood is great if you love the artistic part of Brooklyn, between Bushwick and BedStuy with lots of bars and restaurants to choose from. Supermarkets are also near and the train to Manhattan is just 2 blocks away. The same J line takes you easily to the Airtrain if you have to go to the JFK airport. At night the subway stop may need a little bit more caution if you are not used to this part of Brooklyn but it was safe.
The place is small but cozy with lots of personal touches and most amenities needed for a longer stay.
Highly recommended, would definitely stay there again.
