Valerie was nothing but helpful from the start of my booking. Always answered questions quickly and nothing was too much trouble. The apartment itself is nice it has everything you need for a short stay in Paris. The location is excellent just a stones throw from the Notre Dame, Metro line, shops and bakeries. It is quite touristy around the Notre Dame but we really enjoyed the side streets with all their hustle and bustle and enjoyed some very yummy ice cream.
The only thing to consider is that it is 5 flights of stairs around 90 steps to the top so if your not really mobile this isn't the flat for you. The only other issue we had was noise obviously you are in the heart of a capital city so it's not going to be quiet but we really struggled to get much sleep. We were there over Bastille Day which is a public holiday so this might have added to it. I would take some ear plugs with you. Beds are ok but they are mattresses on the floor again if you are not very mobile probably not the place for you.
We really enjoyed our stay and I wouldn't hesitate to recommend Valerie and her apartment.
