This apartment is truly incredible and perfect for a large family or multiple couples, as each room has it's own en suite, two with a toilet inside and one with a toilet just outside in the study area (but could technically be reserved for that room if needed).
Yes there are lots of stairs, but the small lift works great for anyone with mobility issues. It's beautifully vintage, so treat with care, but it works great.
The common areas are all fantastic and the kitchen and bathrooms were all extremely well equipped.
Communication was great.
The very best part of this apartment is its location. In beautiful Saint Germain, but just a block in from the Seine so you can still walk over to the Louvre and all surrounding spots.
We would definitely love to stay here again on our next visit to Paris.
