My appartement in Paris gets yours in Copenhaguen around end of August (center or Bella Center )

I have to be in Copenhaguen from the 23 to 27th August. Would love also to be there the week before.
My conférence is in Bella Center but a central location is fine to me

My own flat is inside Paris 5 stations awaya from Hotel de Ville
I'm near a nice park (see bellow)
-We can swap flat (mine have 2 bedrooms+ living room + all amenities very calm and sunny)
-Or you choose the time of your stay in Paris and you can use my other bedroom (max 2 peoples) in exchange of one of yours in Copenhaguen
