Martin's place is exactly as described. Bed was firm. No complimentary shampoo or conditioner. The bathroom is tiny and the shower itself has no light. Keep in mind that this is a basement and there are bugs flying around and coming out at night (saw a cockroach every night in the bathroom).
Nevertheless, Martin is extremely communicative and even left us an extra box of tissues when we had run or. The place is a bit dusty and when we stayed on the weekend there was music playing from the neighbors until well past midnight. It's a good location in Bushwick if your plan is to just see the sights and have a place to stay.
