Sergio does not answer on messages, and its very hard to communicate with him even on the phone. He didnt showed up at the apartment at the time he should be, we had to wait for him...
He rent us a room without a window, and thats ILLEGAL in Lisbon, so noone should rent a room at his place!!
A room without a window is not just illegal, its disgusting, there isnt enough fresh air and it smells like hell...
Please stay away of Sergio and his apartment.
