Thierry is an experienced, well-travelled, cultured person. His place is slightly off from the city center but is easily accessible by public transport. There is a bus and metro stop in about 5 mins’ walk. The house is small but very stylish, and you stay on the sofa bed, as mentioned in the posting. It was extremely clean. Thierry personally checked me in, and explained all the main sites and transport lines to me. He even has a small guidebook for Paris. Check in and check out times were extremely flexible, thanks to him. There is a kitchen and he offered me access to the much-needed coffee 24/7 :D. I would definitely go back.
