First of all; the appartment is fantastic! It was easy to find with the route discription Carol gave us. The appartment is cozy and everything you need is there! Also the beds are really comfortable. You can easily stay there with four people!
The location is perfect, le marais is a lovely and safe neighbourhood and there are a lot of nice restaurants and bakery's around the corner. On a sunday it's really nice to stay in Le Marais, because all of the stores are open and there are a lot of people walking around the neighbourhood.
Also the communication between me and Carol before our trip to paris was really good. Everything was clear, and i could ask everything.
Overall a great place to stay! I totally recommend it.
