This is a fantastic flat in a superb location. You are literally a few minutes walk from Notre Dame and many of the central attractions are only a 20-30 minute walk away. There is a great market (most days) on Rue St Germain and a wide range of mini-supermarkets nearby. Although central the pedestrian street is mostly quiet. Those with mobility issues would find the staircase difficult and large suitcases would be awkward.
The flat itself is comfortable and spotlessly clean.
