Amazing flat, exactely the same as the pictures, luminous, warm and beautiful with lot of space. Impossible to do better concerning the location! In the heart of the old town in a famous street crowded the day but very calm at night (and anyway, it's an attic studio, so it's not noisy).
We did not meet Robert (he was not there) but he was very efficient to explain how to come and his girlfriend was there to welcome us. Since everything was perfect during our stay, we did not need to contact them again but they were very accomodating concerning our departure.
The kind of place you would like to keep secret such it's great!
