My host Marc Cohen did everything he could to improve his apartment throughout the time I stayed. I am absolutely impressed by his sincerity and hospitality. For example, I complained that the sofa bed was too thin and slanted, which made it difficult to sleep. He purchased a new regular bed when I was out of Paris. He also replaced the entire shower set and had handyman came to fix a leakage of the shower floor. He was always available if there was any problem. Eventually we became good friends. Over all, I had a wonderful experience staying at Marc's apartment.
