Katy was very good host, very flexible and able to accommodate all our requests (travel cot, check in and check out times, locker to leave our buggy downstairs,...).
The flat is very clean and nice, it has probably been redecorated recently and there is a lift which is not always the case in Paris!
The neighbourhood is very convenient with lots of different shops around for groceries, wine, bread and short walk to several metro lines which is great to visit Paris.
