"I keep in touch with my old neighbors all the time and it sounds like the building has changed hands several times and most recently, we discovered that the owner is possibly illegally renting apartments like a hotel."
The resident points us to an Airbnb listing for a "DREAMY" apartment on St. Mark's Place...
The "approximate" address is 38 St. Mark's Place... which isn't an existing address on St. Mark's Place.
In any event, this particular listing is worth noting for the "house rules," which we reposted below... (The all caps are part of the rules; the bold is our doing)...
PLEASE BE COURTEOUS AND POLITE TO THE NEIGHBORS in the building. They do not want to live with crazy, loud people. Please: No crazy parties or loud drinking! TRY NOT TO TALK TO THEM. DO NOT TELL ANYBODY YOU ARE RENTING MY APARTMENT. DO NOT TELL ANYBODY WHICH APT YOU ARE STAYING IN. JUST TELL THEM YOU ARE A FRIEND VISITING. Please DO NOT TALK IN THE HALLWAYS. If anybody were to ask you something, you are a friend staying with me on holiday visiting New York and you did not pay me money to stay at the apartment BUT TRY TO AVOID CONVERSATION. Please try to be discreet going up the stairs and try not to linger in the hallways
