Helene's place is quite lovely: it is beautifully decorated, very comfortable, and we were very pleased with the apartment. The outdoor seating area in the back is quite nice, and the parking spot was very useful. Helene was also an extremely gracious host: when she learned that I like to swim, she invited me to participate in a Master's swim class, which was very thoughtful of her. Overall, we had a wonderful time during our stay at Helene's place.
There was just one sub-optimal thing that happened during our stay, which is that on our very last night (a Thursday), the people who arrived for a short-term stay in the apartment above us decided to have a loud late-night party (starting at 2am), which disturbed our sleep. We couldn't hear voices or music, but they were stomping and jumping on their floor so much that we could hear that through our ceiling. I eventually went upstairs and talked to them, and they quieted down after that. This was not Helene's fault (and not a reason to avoid renting her lovely apartment): it was due to the short-term visitors above us being inconsiderate. Again, we had a very nice stay overall, and I do highly recommend Helene's apartment.
