I am not the listing broker of the rental and I am not sure if she is an active member of Trulia Voices...
Since the unit is still occupied by a tenant, it might be that they did not want any pictures taken of "their" bedroom or anything like that.
As far as your TV question goes: I am sure there is a TV hook up in the living room and at least one bedroom. Since this is not a furnished rental, I am assuming that there won't be any TV sets inside the unit when rented.
Feel free to contact me if you have further questions or if you would like to view this unit - or any other on Key Biscayne! I am happy to help you find the rental you are looking for!
