Alain's house was perfectly located for my needs and also generally speaking. If one likes to walk it is only a very pleasant 20 minutes walk to the seine and close to some very interesting areas of Paris. Metro station is right in front of Alan's building and bus no. 67 takes you right to/from the very centre and even on to Pigalle.
The house is very cosy and full of character, and Alain's hospitality really makes you feel at home. SUPER RECOMMENDED!
