Kathryn's place is lovely, super clean and most of all cozy and comfy. Sleeping on a proper bed does make a world of difference when you have back problems like me, especially on a fairly long stay. This one is very comfortable, plus it has columns and curtains :) Kathryn has been very helpful with food tips and quick in replying to all our needs.
The apartment is very close to the C line (5-7 minutes walk), so it's quite easy to get around Brooklyn and Manhattan. I would totally go back even just to sleep on that bed!
