This is all the more reason to contact OTA. The more complicated your situation is, the more you want expert advice, and they’re literally the experts and in your side.

That said, yes, you likely have rights as a tenant. That your sublessor didn’t have permission to sublease doesn’t likely change whether you have rights, and you’ll want to talk to OTA about rights with respect to your current apartment, the management company, and the sublessor. It’s not your fault they broke their own lease with the management company to sublease to you, and you probably have rights you can exercise in this situation.
