We had a great experience staying with Guy! The apartment is very conveniently located- it was very easy to access the city center by public transport and Montmartre is just a short walking distance away. Guy keeps the place very clean and neat and most importantly, he's just great company and a wonderful host, very helpful and accomodating. As I was traveling with a friend and we needed 2 separate beds, Guy put us up in his room rather than the usual guest room (which is equipped with a queensize bed). This was completely fine except for the unreliable WiFi reception in this particular room- in the rest of the apartment it works perfectly. This was more than compensated by the fantastic Italian coffee Guy prepares in the morning and the wine he was very generous to offer us. All in all staying with Guy contributed a lot to the great experience we had in Paris. Absolutely recommended!
