I stayed with Tristan and Manuella for one night between airplane and catching a train to Brittany. Their apartment is a few hundred feet, if that, from an entrance to the Gare Montparnasse, so it was a perfect location for my purposes. More than that, they are perfect hosts. The apartment is sparkling clean, the bed comfortable, and there is a fascinating view of the busy streets around the train station. It is a very short walk to a Métro stop, and there are plenty of bakeries, restaurants, and grocery stores in easy walking distance from their flat. Tristan was an excellent communicator, and both he and Manuella speak excellent English. I flagged in energy and even felt a bit ill after my hours of walking around Paris, and asked via text if I could return to the apartment in the afternoon. No problem! And very gracious about it. I only wish I could have had more time, and been in better shape physically, to get to know this dynamic young couple better.
