Great location and place to stay. We spent 3 nights there and the house has all the facilities required. Well located, decorated with taste, we had a great time at Elena and George's house.
Nevertheless, it's important to note that being a loft the 2 bedrooms are opened, hence a lack of intimacy if required. Also, the bed downstairs felt uncomfy for us, we felt the springs all night long.
On the other side our teenager loved the place and mentionned that he would love such a place in Paris :)
