Myself, my brother, and cousin stayed at one of Michael's studios over New Years and it was a wonderful stay! Michael was more than accomodating, making sure that we had detailed instructions on how to get to the apartment. He was there to meet us when we arrived at 10:30pm and provided us details on nearby attractions, grocery stores, metro stations, etc. If needed, he was always prompt to respond through email correspondance as well.
Michael is a very welcoming and hospitable host! We will definitely be looking him up the next time we're in Paris!
