Max's place is very well located. It is a 5 minute walk from a metro stop and it is surrounded by lots of food places, a gym next door, and a market next door. We walked back late one night and felt very safe.
The flat itself was very nice! It was spacious, the bed and sofa bed were very comfortable. Lots of light came into the flat and if you didn't want the light the electric shades were wonderful!
Although we did not get to meet Max, he always responded so fast to any messages and questions.
I would recommend this very well located flat to anyone visiting Paris.
