96 Rockwell - questions on condos

FortGreener - I read your recent comments re: 96 Rockwell and wanted to know whether you can clarify a few things? We are considering a unit in the building (in the extension on top) and wondering if the same issues you suggest re: A/C leaking, floors buckling, etc. are in that section of the building or just the original part (floors 2-6). Also, we've found the sponsor to be somewhat unresponsive on questions...is that your experience as well? Finally, I'd heard at some point that most of the 2BRs had been sold in the extension, but I live in the neighborhood and haven't seen any signs of life on those balconies. Do you know whether the sponsor is full or it or if there are problems with those units? Thanks in advance!
