Laura is incredibly considerate and I can not recommend staying with her enough. She is very conscience of her presence (she sleeps in the common room on the couch, but is very open to getting up early if required and giving guests space). She has extra touches like toiletries for those who need it and an amazing patio with a bunch of beautiful plants. Her cats are both incredibly sweet. She has lots of books and is happy to lend them. The gym in the building is usually empty and is clean—it has treadmills, elliptical, mats, weight machines, and some free weights. The location is very convenient if you have business on the upper west side, as it is 2 minutes from the 145 1 stop and also very close to the M11 bus. Great for Columbia students and guests!!!! Thanks so much Laura. :)
