I was lucky to spend two days and nights in Bi's lovely home in Brooklyn Heights. The room I rented is a three stories' walk-up from street level, but I did not mind the few steps up the stairs at all--I was rewarded by an extremely quiet room overlooking the backyard and the neighboring Brooklyn Heights brownstones. The room is exactly as charming as advertised in Bi's pictures. The wifi worked flawlessly and fast, and I enjoyed working for about eight hours on the little desk in the corner of the room. The bathroom and some other common space are shared with other guests who may be renting either of the two other rooms on the floor; this was a non-issue for me, possibly also since there were in fact no other tenants on my floor while I was there. Bi's place is ideals, the room is affordable, and I hope to be back soon. Bi is a wonderful host who lives and works in the building, and she's extremely accommodating and helpful.
