I highly recommend you to stay at Clémence flat because:
1) Rue Flatters has a very nice location. It’s close to the Latin quarter and Notre-Dame (about 30 min by walking). The place is very silent and is provided with all types of transport, so you can go wherever you want.
2) Clémence is very helpful and ready to give you advice on your stay in Paris (restaurants, Parisian way of life etc). She even has invited us to her theatre that we enjoyed a lot!
3) We had everything during our stay: towels, bed linen, everything for shower, tea and the whole room with a sofa, chairs, WiFi and sockets.
