Wow - my fiance works on the UWS and as part of his job he has keys to his clients apartments so he can get in and out during the day. I know he has several clients in the 70's. I am going to look up the addresses in his database when I get home tonight to see if any of them live in any of these addresses. I assist fiance sometimes when he needs help and stay at clients apartments so it is surely in my best interest to figure out if there is any association. So scary for the people who live there.
At my apartment building the super does not have keys to our apts. If they ever have to enter during the day for maintenance work we have to leave our keys with them.
A little OT:
Songline - you are a broker? So, when I am in the market for another apartment you would be happy to wave your broker fee right? The ol' Websleuths discount?
