Really enjoyed staying at this brownstone, was conveniently located and close to all amenities. We were a group of 7 (4 in one double room, 2 in the other, and a 3rd on the sofa bed) and with two bathroom's this was ideal. We stayed for 6 nights with no major issues. The neighbourhood was lovely and had choice of cafes and convenient stores nearby which made the morning walk for coffee very pleasant .
The subway was less then 10 minutes away and a metro ride into Manhatten taking around 20 minutes or so (depending on which train you got). We hired a car towards the end of our stay too (as we were taking a road trip) so it's worth noting there's free street parking which was great, but space is scarce and be sure to read the signs for parking restrictions due to street cleaning, as this willl warrant an unwanted fine!
A few points worth noting however is you can hear your neighbours stomping around in the apartment above. I found there to be a lack of crockery, pans and drinking glasses (as only beer stein's were available). Cleaning products were limited, and only a handful of dishwasher tablets available, the hand soap ran out and had to he topped up as well as no detergents or toilet cleaner. These however are all minor details that I'm sure can be rectified easily.
Hong's apartment is as described and very spacious. Checking in and checking out was straight forward with no issues. All in all our group had a very pleasant stay, I would stay here again if visiting New York and would recommend to others too!
