My 10 day stay in Nicolas' apartment was perfect. The apartment is very clean and comfortable on an inside courtyard with a tree outside the window. There is plenty of light. The sofa bed is quite comfortable.
One can find all the necessary shops and restaurants nearby as well as transportation. I walked to most places.
Nicolas was communicative and had no problem waiting for me despite the fact that my arrival was about 1 hour late.
I highly recommend staying in Nicolas' flat.
