We had a wonderful stay at Himanshu's flat. Centrally located, however a bit of a walk to local attractions. It was about a 10 minute walk to the subway and Pompidou and 15 - 20 minutes to Notre Dame. The flat was exactly as described and depicted in the pictures! They left us ample supply of Nespresso and it was just what we needed adjusting to the time difference. Didn't get to meet Himanshu, but checked in with Mrs. B. Sweet lady, but a bit tough to communicate as her English was limited. Easy, convenient, flexible and correspondence was easy. Minus the spotty wi-fi, we'd definitely recommend the flat!
Extra tips: If arriving from Orly, we took the train then hopped in a cab. It might have been worth just spending the money for a cab directly to the flat. Taxi is easiest to haul on the main street across from Pompidou.
