Staying at Tugdual's place was, for the most part, as I expected. Like others mentioned, I only saw him when I checked in and no interaction with him thereafter. The only evidence you had of Tugdual being there were the sounds of the creaky floors and doors opening/closing.
Good location very close to the Arc De Triomphe and Champs-Elysees, as well as one stop away from the Eiffel Tower. I found myself wandering around the 5th and 4th arrondissemonts during my stay. I would 100% recommend Tugdual's place for the solo traveller in Paris.
