Our stay in Catherine's place was really nice: the place is clean and a very short walk from the streetcar (2 blocks away). Furthermore, Catherine is very friendly, quick to respond, flexible (she allowed us to drop the languages earlier) and makes awesome suggestions (you can find a list of suggestions of restaurants in the kitchen and, on a whiteboard that she updates every day, a list of the best musical venues and special events occurring the next day). I would definitely recommend this place
