Ralda and her brother Alex were very helpful at every moment. Our arrival was late at night (9pm) and Alex was patiently waiting for us. He gave us local tips and all the instructions. The building is in front of the metro (line 12) which is a plus...specially in cold weather. A local supermarket is half block away and it is near nice French restaurants. It is a very good way to experience French every day life and not end in tourist traps. I particularly enjoyed renting a bike for a day and having the opportunity to have a safe space in the building to park it.
