Why you are still looking for the comments, if there is a space available for you, you should definitely stay at Genny's place. Genny is the best host I have ever had, and her place is great. Genny is very friendly and is willing to talk with you whenever you have question.
1) The location is great and very close to Columbia University. It is about 10 minutes walk to the main Campus.
2) The apt is very new and the neighborhood is great. The room is very comfortable.
3) The apt is pretty and every piece of furniture is great and you could totally count on the pictures.
4) You will have your private bathroom and it is very clean. Bath robe, bath towels, shampoo, conditioners are ready for you.
5) Genny also provides some grocery for breakfast. She had Croissant, milk, yogurt for me in the fridge.
I will definitely stay with Genny whenever I visit Genny. Thank you.
