Valerio is a kind and attentive host from the first moment. He sent all the information i needed about checking in 1 week before my arrival. Apartment was comfortable (if you are ok to crawl on mezzanine :)) and clean. Wifi works perfectly. Sufficiently equipped kitchen etc. Location is great. There are many bars and restaurants around (in 2 minutes walking distance) and a Carrefour literally 3 steps across. Subway station in less than 5 minutes walk. Notre Dame is less than 10. It was really fun to stay in such a central part of Paris.
