My mom and I had a lovely few days staying at Boris's apartment. It's the perfect place if you want to say right in the central of Paris.
Two metro stations are just around the corner and will take you basically everywhere in Paris.
We also found some really amazing restaurants and bars just around the corner which where great for dinner in the evenings.
If you want to go out at night there are a lot of bars in the street as well as around the corner. Therefore it can be kind of noisy in the apartment until the middle of the night. But the windows cancle out a lot of the noise from the street if you keep them closed.

Boris was a great host! He met us right at the apartment when we arrived and showed us how everything worked.
The sofa bed is not the most comfiest, but definitely okay for a few days.
The bathroom is great too - a nice big shower :).
Thanks for having us Boris.
I'll definitely will come back to Paris.
