If you are thinking of buying on Manhattan’s upper west side, maybe you should take a look at 370 Central Park west. The 6 story co-op at the corner of West 97th street and Central Park west is a small building with a lot to offer. 370 CPW has a great staff, is pet friendly, well managed and has an interior garden for residents. The building is full of charm and some of the apartments have wonderful details like moldings, casement windows, and even fireplaces.
Unfortunately, the only availability in this boutique building with just over 70 residences is a rental for $5700 per month. Having been in several of the apartments, I would recommend to get something on the sixth floor if possible because of the high ceilings or an apartment with a view of the park. Those do not come up that often so if it does, get ready to pounce on it!
