I live in Paris, working in Marketing. 30 years old.
Had a lot of difficulty in communicating with Matthias re:heating. Tried to coordinate a time to help him switch on the heating which works extremely well and efficiently. Alas, communication went unanswered and eventually gave up. Then told privately that he had been scammed even though I went out of my way to accommodate his friends and him. Left the place in a mediocre state. Insulting. Sorry, I cannot recommend.
