Great option for traveling with a large group.
Pros-
This was a very spacious apartment. Six of us stayed here for almost a week and we didn't feel like we were on top of each other. There was plenty of room to spread out.
Eleonor is very responsive which was helpful when we had to check in later than expected because our train was canceled.
The apartment is also about a 5 mins walk from a metro stop that connects to a lot of popular tourist spots in Paris.
Cons
This apartment is not in Montmartre. It's two metro stops away and a completely different vibe.
So keep that in mind, if that's important to you.
The neighborhood was a bit crowded with people standing around the corners most days and had a different feeling from other parts of Paris. I got more comfortable being there after a few days.
The bathroom situation is not ideal. The shared bathroom had a spa tub which was not ideal for showers at all. No one used that bathroom so all six of us had to coordinate using the shower that's attached to one of the bedrooms.
Keep that in mind if you're traveling with people who aren't that close and wouldn't want to be going into each other's bedroom.
Also, I don't think I'd be comfortable bringing children to this apartment. There is a lot of glassware and other decor that I would be worried to have children running around.
In all, it was a really good value for the money and gave us a big space for our family.
