Fred was a great host--he made sure we would be well taken care of when we came, and communicated well with us in the month or so before we arrived, offering helpful info on restaurants and music in the area. And his place has so much character to go along with a very comfortable bed and beautiful skylights and balcony.
The neighbourhood (Pigalle) is really funky--l=plenty of nightlife within short walking distance. Very convenient for getting about on foot or via the metro to everything we wanted to see in Paris!
All in all a highly recommended experience!
