We had a fabulous stay in Marine's beautiful loft apartment. Marine responded quickly to all our enquiries, and her suggestions on where to go and what do to during our time there were excellent. The location of the apartment is wonderful for exploring Paris easily and the apartment is great for families. The kids loved their upstairs domain. I would definitely recommend it to anyone visiting Paris with kids or without. The apartment is on the 4th floor, we didn't find the stairs a problem, but some might do so.
