While Michelle is a prompt communicator and I appreciate her efforts to address any concerns, the building is older than the pictures convey. There had been pipes leaking on rainy evenings prior to that, but when alerted to Michelle, it does not appear she had the leaking ceiling checked out. Half the ceiling of the 2nd floor bathroom then collapsed in the bathtub on a heavily rainy night the third week of September.
Being in an old building, you should also know that the floorboard will creak, the staircase is narrow - rough for bringing up anything larger than carry on suitcases - and there are mice when the weather is cooler. The third floor guest ran into mice and one of em made it into the second floor guest bedroom where I stayed.
Most of this is not necessarily a reflection of the host: Michelle did schedule cleaners and repairmen when the bathroom ceiling collapsed (though hopefully the fix of cardboard/ducttape/trashbag is just temporary by the time you stay there). Just be aware you'll stay in an older building with pre-existing problems that may catch you off guard during your trip.
Room is pretty spacious with microwave, mini fridge and dishes. Michelle lives on the same floor and doesn't appear to use the bathroom so that's mainly all yours. Extra bed in closet. Queen bed in main room. Main suggestion is to remove a few of the old, yellow-stained chairs and unnecessary appliances like alarm clock and a box fan (you already have an AC unit). First floor guest at the time mentioned her unit has old furniture reminiscent of a junkyard.
Location-wise, this is a 10 min walk from 3 subway, then another 2 blocks away from 2 and 5 subways. Nostrand Ave has plenty of 24 hour delis and solid Caribbean and Americanized Chinese restaurants. Some good bars and convenient groceries.
