I'm staying with a yogi while I'm in NYC. Meghan Nichols is highly recommended for classes and private sessions!!! You can check out her website here: http://meghannichols.com/Welcome.html
So far my favorites have been private restorative yoga (my kinda thing! so relaxing!) and her Friday at 12:30PM Yoga Blend class at Sports Club LA Upper East Side, which strikes a perfect balance between difficult and soothing. If I were staying in NYC I'd like to work privately with her on my hammies and I'm dying to try her Zenyasa class.
