Ben and Lucia's apartment is beautiful, bright, and spacious. We loved the skylights and the light in the apartment even in December. The location right near the Canal St. Martin is fantastic -- this is an interesting, vibrant neighborhood with lots of restaurants, cafes, and shops. The canal is pretty and would be a nice place to hang out in warmer weather.
Ben and Lucia were always very responsive and pleasant to deal with. The cleanliness issue we encountered was that the sleeping area in the loft was so dusty that one of our party had to move downstairs and sleep on the couch the whole time because of a massive allergy attack. But over all this was a lovely place and I would definitely recommend it.
