I stayed in Marthas room for 6 nights.
The description of the room is quite accurate (you have a private toilet and a private shower which is really nice!). Note: This is a real persons private room, so expect a lot of personal (girly) items. Martha was very responsive and nice to talk to. In the house, there are also other people (shared kitchen) but they were all really chill and welcoming.
The house is located close to the Myrtle subway station (J,M-Line) which makes it an easy staging point for trips to Manhatten. Overall, I would book her AirBnB again!
Cheers!
