We had a wonderful time here - absolutely stunning location in the heart of Paris. The Merveil-Team is extremely responsive but also requires quite a lot of information prior to arrival. During the stay itself, the team answered all of our questions immediately and even provided us with extra blankets (for the super cosy beds). They also helped us with information on where to store our luggages after checkout. We were a group of 9 people and everyone had enough space but you should feel comfortable with sharing the 2 1/2 bathrooms of course. All in all a lovely experience - highly recommended!
