Lilian and Juan Esteban are much more than really good hosts. They provide EVERYTHING a person who have never been to the city needs to get along with the place (that was my experience!). The apartment is pretty clean and well located, especially for those who are going to observerships in the NYP Hospital - Columbia University . I should also say that is a very suitable place for those who are going to the Allen - Spine Hospital. The shuttles for all the Columbia locations depart 2 blocks away, just in front of the NYP Hospital on Broadway. Moreover, there are 2 subway stations not further than 3 blocks away from there (lines 1,A,C) which give you the chance to explore almost the whole NYC, from the JFK to the very top of Manhattan. There are bus stops all around and also supermarkets, pharmacies, food shops, gyms, pathways to go jogging and cycling. Honestly, I stayed 3 months in Lilian and Juan Esteban's home and for me they're more than 5 stars all the way there. I do recommend and, of course, I hope to come back soon!
