Marianna is a really nice host. Extremely quick in responding to messages and very helpful.
The place is in line with NY standards as far as space goes. It is extremely clean and tidy, and Marianna wants you to keep it that way (rightfully so).
The bed is reasonably comfortable, although I found that the curtains were not really able to keep light out (wasn't a problem for me as I woke up early every day).
Subway station (L line) is 12 min walk, bus station is around the corner.
Price is good for what you get, I can really recommend it for visiting New York.
