They were great hosts! We did not see them much because our schedules did not align but Alexandra still went out of her way to help us. She even made a reservation for us and my parents at a very poplar local restaurant. She also gave us some excellent suggestions for restaurants and museums.
The room was small for our American tastes but according to our travel companions, it was about the same size as a Parisian hotel. Besides, the point of being in Paris is to see the sights, not spend all day in your room. The private balcony was cozy but we didn't get a chance to utilize it due to the rain. We had our own bathroom that was small but we made it work with little difficulty. The wifi was a little spotty due to the age of the building (it works better in the kitchen/living room), but Netflix worked like normal in the bedroom.
The place is near several metro stations and is just far enough away from all the heavy tourist areas.
Overall, we had a great experience and would use them again next time we are in Paris.
