We really enjoyed staying in Heide's home. We never met Heide, but communication was really good and check-in was easy and problem free. The flat itself, although small was lovely - really homely with a well equipped kitchen. Very easy to cook here, if you want to stay in - there's even an oven and basic provisions to use. Location is great. Very easy to reach from Gare du Nord (4 stops on the metro) and good bus connections as well. Heide also left a good list of local recommendations. Highly recommend.
