We (a group of three friends) had a great 2 nights' stay at Alexandra's place. The apartment was very clean and cozy. It was located downtown, within a walking distance of many cafes and bars, and the main shopping street; however, we did have to use Uber to get to Mont Royal and to Saint-Louis Square, for instance.
Alexandra was kind and super fast to respond to my messages regarding check-in and check-out. We had all the amenities we needed, although we did not have the time to check out the pool or gym in the building. On our last day, we arranged to leave our bags for a few hours at the building's administrator's office downstairs, paying just a few dollars each; that was really handy. We would definitely recommend Alexandra's place to other travellers.
