Inna is a great host, very available and always there for any issue or trouble. I had the pleasure to stay in Inna's apartment for 4 months and the experience overall was good. As a Columbia student, the position is just perfect (10-15 mis walking distance from campus), however the neighborhood can be a little sketchy. The apartment in the pictures looks bigger than it is in reality and it is overpriced for what it is. Enjoy your stay at Inna's!
