I had a terrific two-week stay at Leticia's and Jeffry's apartment. It had everything I needed. The apartment is clean, you can use the living room and kitchen, and the small bedroom (with a desk) met my needs. The Wi-Fi was fast and reliable. I enjoyed the free use of one of their bicycles. As others have written, the apartment is in a terrific neighborhood. Among other things, there are many excellent restaurants and bars, a wonderful café two blocks away, a reasonably-priced supermarket several blocks away, and a great jazz club that you can walk to in a little over 10 minutes. It takes only a few minutes to walk to the nearest Metro station.
What made the stay especially nice was the friendliness of Leticia, Jeffry, and their apartment-mate. They offered many helpful suggestions. Beyond that, it was a pleasure to talk with them about Montreal and all kinds of other topics. I definitely would stay there again.
