Rose-Marie was a lovey host; she was very communicative the entire time. She met us and greeted us upon arrival, and even gifted us with some wine and champagne (for the New Year!)
She would come and take our dishes and trash everyday; this didn't bother us, but if you are someone who doesn't want to be intruded upon or have the host able to come into the space, then a heads up.
The street is very quiet and we all felt very safe. The train does go by at night, but that didn't bother us. However, the three of us were woken up consistently between 1:00 and 3:00 AM every morning by pacing upstairs (even with white noise machines and fans). So, if you're a light sleeper, maybe consider bringing some earplugs or headphones.
All in all, a lovely experience, with a lovely host, for a lovely value.
