I stayed at Ryan's Flatiron studio for 10 nights over christmas with 2 friends, and it was excellent. The apartment was exactly as advertised, had all the comforts of home and was in close proximity to the subway and some awesome bars.
During our stay, Ryan was out of town so his friend Paul was our contact. Paul was extremely helpful with our many questions and gave some great recommendations on places to go around the neighborhood too.
Both Ryan and Paul responded to queries promptly and were fantastic hosts and i have no hesitation in recommending this apartment.
