We had a wonderful time at Heide's apartment. It is very clean and tidy and plenty big enough for the two of us for six days. The bed is comfortable and we did not find the stairs at all onerous (except perhaps on one day where we had walked over 12 km at Versailles!). At least three bakeries less than 10 minutes walk away meant that breakfast and dessert treats were a delight every day. Though slightly away from the heart of Montmartre, everything is close enough to be easily accessible, with less than 20 minutes walk to Sacre Coeur. Most days we started our Paris exploration with the 5 minute walk to the Simplon Metro station. Heide's instruction manual is very complete and she answered our queries before arrival very promptly. All in all, highly recommended.
