Travelling Roosevelt Island Resident Seeking Island House Rent Payment Address - Can Anyone Help?

A travelling Roosevelt Island reader sends in the following request for information:

I am currently an RI resident on extended honeymoon. I neglected to get the mailing address for rent checks for Island House on Roosevelt Island. I have looked all over the internet and on many RI sites, but cannot find it. As I have also been asked this question by a fellow resident, I thought it might be a good idea to post it somewhere on your site.

I cannot even find an email address for them. Perhaps posting that might be worthwhile, too. As I am in the southern hemisphere and constantly on the move, the timing for calls is quite difficult...considering many "public" phones are actually phone services stores with business hours, of which we are having difficulties getting to on time.
Your information is greatly appreciated.

RIOC has a list of addresses and phone numbers for Roosevelt Island housing companies here but no email address.

There is also an Island House residents web site but it does not appear to be active.

Can anyone help?
