The house is really big (we stay in 3 people, but it is suitable for more people) and very comfortable. Also the sofa can be transformated into a confortable bed. Staying in this house is like staying in your home. Everything was really clean.
If you are 3 people or more, I suggest you to book this apartment, it was perfect for our stay, you can go walking to Eiffel or just take RER or Metro to go everywere in Paris. At floor 0 of the building there is a supermarket.
If you stay here, just remember to leave a message in the boy room ;)
