I stayed here with a Patricia's son for last two weeks.
Whenever there were issues, Patricia and her son tried their best to deal with the problems. They are really friendly, so if you need any help or need ideas of planning trips in NYC, ask them freely!!
The best thing about this place is location. There is 191 st station right in front of this place and it connects to nearly all areas in Manhattan.
Also, for your laundries, you can go to either basement or coin laundry that is right across the street. I recommend using coin laundry because it tends to get busier and difficult to find time to do your laundries at one with the basement.
Thanks for your help. Had such a wondeful time at your place!
