I spent almost a week at Roman's appartment, and was quite happy with my stay.
Honestly it is not bad, given that this is in Paris. The apartment is in an ancient Parisien building with lift. As it is Roman's home, all essential things are equipped, and most importantly everything functions ! unlike some superficially nice and super expensive airbnb appartments in Paris...trust me, I had quite a few bad airbnb experiences at the French capital...
I also enjoyed very much l'ambiance of his salon. very soothing.
Another plus is the bed is very comfy, a good king size, larger than most European beds in the airbnb appartments.
Need to walk about 10 mins to MTR stations.
