Catherine's place is full of character and special touches. You really feel like you're staying in someone's home. If the weather is good, she has several windows you can open, which is really nice.
There are plenty of great shops + restaurants in the area, but if a lot of your activities are across the river, your train rides will be ~30min. Crossing the bridges everyday was nice, though, and there are a couple trains the come fairly close to this apartment.
