We were hosted by Samantha since Sheena was traveling, and she was great! The room is small but WOW they've really managed to maximize the usable space in there so that you wind up not feeling cramped at all. Lots of smart little hacks, in addition to some really useful things (extra chargers and adapters, little snacks) for the traveler who may have forgotten something. Having our own bathroom was amazing, and the A/C was key for our comfort. The neighborhood is great fun! The flat is just a couple of blocks from the metro, and just a block away (in one direction) from delicious coffee and (in the other direction) vegan ice cream, so we were set for all of our needs. I should also add that we never felt unsafe, although people who aren't used to cities might not feel totally at ease walking home from the metro at night.
Overall we had a wonderful stay with Samantha and would recommend the flat to anyone who wants to get the flavor of NYC living without the total hipster vibe of some of the other Brooklyn areas or the massive tourist onslaught of Manhattan.
