Katie and Matthias place is amazing. The flat is very stylish and has everything you need. Katie and Matthias are also very welcoming. Even though I didn't meet them personally, they regularly checked that I had everything I needed. The bottle of wine and the French flags in the garden made me feel very welcomed.
I was there for a conference and so the flat was ideally located for me (30 minutes by walk).
The tops of the flat: the deco, modern equipment and tv with Amazon fire, Netflix, etc. !
I highly recommend Katie and Matthias's place!
