The place is very clean, well-equipped, and located in the midst of great restaurants, cafes and stores. The bed and pull-out couch are super-comfortable, and the host is responsive. We enjoyed eating and having a glass of wine on the little balcony.
The reason I didn't give five stars is that using the private garage (extra CA$15/day) was an uncomfortable experience, due to an unfriendly building staffer who played the role of the troll in the story of the Billy Goats Gruff. We met him when we had difficulty getting the remote to signal the door to lift. As he was standing nearby, presumably waiting to see if we followed the proper secure-exit procedure, I hopped out of the car to ask his advice. "I work for the building, not the host," he said coldly, adding that it was the host's job to explain. We finally managed to get the door opened on our own, but that encounter left a sour taste and an impression that there's tension in the building over units being used as vacation rentals. I feel bad about this, as our host was diligent in explaining the rules of being courteous guests.
One other caution about the building: There's a note on the elevator explaining that it malfunctions in very hot weather. My husband and I prefer taking the stairs in any event, but not everyone is willing or able to hike up or down from to the fourth floor. As periods of high heat are increasing, this quirk in the elevator operation seems worrisome.
