WOW. We were a group of 10 people and stayed in both of Augustin's properties - My Skydome and My Veranda.
First of all, you can't beat the location! Close to the Marais, Canal St. Martin, etc. The apartments were easy to access, and the instructions from Augustin and his team were crystal clear.
The apartments are fantastic - VERY cool layouts, and everything is brand new and purposeful (ie. the long dining table has outlets). The upstairs has a pool table, bar, and sitting area. The rooms themselves have great layouts, with comfortable beds, lots of close space. The bathrooms are modern with GREAT water pressure. Not what I would expect in a Paris apartment. There's even a gym and sauna! It would work really well for groups for business or pleasure.
Our group was in Paris for a very special and important occasion, and the hosts were so thoughtful and left us a really lovely card and champagne. Additionally, I had asked Augustin about restaurant and chef recommendations since we were such a large group, and he immediately got back to me with some great options.
We were so thrilled to stay in this gorgeous space, really appreciated how helpful our hosts were, and I will absolutely try to book it again the next time I'm in Paris!
