Leo was very responsive and communication was good. The studio is located on a hilly side street and had a sketchy dark entrance of 2 doors and a set of stairs. (be aware if you have heavy suitcases) The immediate neighborhood had some nice shops and restaurants within walking distance.
The downstairs space in the studio was fine, but the bedroom loft was very tight and cramped because you are unable to stand to access the bed, which is actually just a mattress on the floor. Once you lay down on the mattress, you must roll off it and stoop over to avoid hitting your head. My wife slept closest to the wall and tried to get up in the middle of the night and banged her head on the ceiling (She's only 5'1"). The mattress was uncomfortable so we did not sleep well. I would not recommend staying here if you prefer more comfortable sleeping accommodations.
It is a 1.5-2 km walk from the studio to the Fairmont Le Château Frontenac. If you are driving, the parking space is about 1/2 mile (.8 km) from the studio which is manageable, but it was raining during my stay so I Ubered to the lot when picking up my car.
