I would highly recommend staying at Rene’s place. The location is perfect, there are cafe, restaurants, bakery all down the street and it is close to a metro station to easily see all the sites.
The apartment is very roomy for our family of 4 and the air conditioning unit in the bedroom was a plus during those hot days.
Rene was very helpful in making checkin arrangements because we were arriving very late on an international flight.
We would most definitely stay here again on our next visit to Paris.
