My experience at the Mi Casa Tu Casa house was great.
The night my friend and I arrived, our super friendly host showed us around the elegantly decorated historic house, which was built during the civil war period and expanded in the 20th century. Bedrooms for guests were upstairs, but we could also use the kitchen, living room and backyard on the first floor. Each floor had one bathroom, but there was only one other guest room on our floor, so there was not much inconvenience. There was a small fridge, a television and an electronic alarm clock in our room--the Spain room. (I think the name came from the decorations in the room.) The room had no desk or chairs and was a bit dark, so it was kind of hard to find a comfortable posture to use my laptop, but if you do not need to read or use a computer the place should probably be quite cozy.
The host also gave us very useful information such as how to find our way around the Bronx and get to different parts of New York from nearby subway stations. The nearby diner that he recommended offered nice hot breakfast.
I visited New York during the weekend to go to the immersive play Then She Fell, and was merely looking for a safe, not-too-expensive place to stay when it came to housing. Mi Casa Tu Casa was a very happy surprise!
