This flat is in a great location, close to the Métro and a lot of great restaurants. Philippe was diligent at making sure he was there to let us in on arrival, even though we turned up hours before the official check-in - this was much appreciated!
We really enjoyed our stay, and thought it great value. However, you should look elsewhere if you have mobility issues (the flat is on the third floor and there's no lift), require a comfortable bed (there is only a sofa bed) or need a lot of space (space comes at a premium in central Paris!). Also, to confirm some other reviews, there was building work going on adjacent to the unit, although it was not audible within the unit and did not really impact us.
We had a great stay though - I would recommend this place if you are happy with the above caveats!
