We couldn't have asked for a better location! There are many wonderful restaurants and shops within walking distance, you're only a few blocks from some major attractions like Notre Dame, Saint Chappelle and Jardin du Luxembourg. Also, being a short walk to the Metro station meant that the rest of Paris was easily accessible to us.
The flat was clean, looked exactly as it did in the pictures and was a comfortable spot for 2 adults to stay for a week. It was well appointed with the basic necessities needed for a stay. There even was a hair dryer! Elisabeth was very responsive to us and found that check-in and check-out easy.
The only thing to keep in mind is that with the great location, comes street noise. The flat is on the 2nd floor and there are a few spots on the street that get pretty busy at night time! If you are an early to bed type of person - you may be bothered by the street noise. Given that Paris is a big city, and this flat was so centrally located, we expected some kind of noise and didn't detract from our experience at all.
