Ikkyukim was great - he met me at the door with a cold beer when I arrived. He showed me the room, and provided me with a key to the front door as well as one to my room, which I could lock when I left.
The house itself feels more like a hostel than anything else - the rooms are sparsely furnished, with little more than a mattress and a box spring on the floor. An air conditioner in the window is a nice touch though. I stayed for 9 days, and on more than one occasion I came home after dark and all the lights were out, and the fire alarm was going off but no one was trying to turn it off or see what was going on - which made me wonder if Ikkyukim was around at all.
The neighborhood was easily the worst part of my stay - I have lived in cities most of my adult life, and I'm not a small or timid guy, but I was uncomfortable walking from the subway to the house at night. Before staying here, do some reading about Hunts Point - while the nightly rent here is low, you pay for that in the neighborhood you will be in.
