I can really recommend this place. Me and my family (husband and kids 6 and 8 yrs old) really enjoyed our stay at Mathieu and Guy's beautiful apartment in central Paris. Everything was nice and clean and even better than we had expected. Cool old wooden floors, generous ceiling height and modern kitchen + bathroom/toilet. Very convenient location. We arrived at Gare du Nord and after a few min walk we ended up at the right address and the check in procedure was quick and easy. We had a few questions during our stay and Mathieu always replied quickly. We especially appreciated that we were allowed to store our luggage/check out later on the day we left, since we had a late flight back home. (The kids especially appreciated the tasty chocolate spread (Nutella-but-better) for breakfast). Thank you!
