There are several things that are going for Vivianne's place. First and foremost, Vivianne's team is extremely responsive. Other than questions I've sent at night, I don't remember a time they don't respond within 5 minutes. Super fast and helpful!!! Second, the place is well located. It is just a few minutes away from three different Metro stations and two bus stops (probably more). No place is perfect. Vivianne's place is on the 5th floor and is only accessible via an elevator because the door to the staircase is locked on the ground floor. If the elevator is broken, then you will have to wait for someone come down to open the door. I mentioned this to Vivianne. Hopefully, it will be remedied soon.
