Franck's house was an excellent base for our stay in Paris. Being a little way out from the centre didn't cause any issues with both the metro and bus within a 5 min walk and the main attractions only 1/2 hr away. The house is located in a residential area with easy access to shops, bars & restaurants (just beware that for those used to 24hr shopping, as with most of France supermarkets only open until 12:00 on Sundays and only until 9:00/10:00 in the evening).
Checkin and checkout were both very simple and communications with Franck both prior to and during our stay were excellent.
