Tristan's place is lovely, a stylish family home with an incredible view all over Paris. It's walking distance to lots of lovely shops/bars and restaurants in the Marais. His communication was excellent and he was very friendly and warm. He let us keep our cases in the apartment on the last day, which made a big difference as we weren't getting the train back to London until late.
We picked up the key, which was a little tricky if you didn't speak French, so I would suggest clarifying check in details with Tristan first, who has excellent English.
He also left us a lovely bottle of wine, which was much appreciated.
