Boris is an amazing host! He is so thoughtful in many ways - he did my laundry for me, checked on me every day to make sure I was alright, gave me advice of things to do in Paris, constantly cleaned the place, responded promptly to all my questions,etc. The location is perfect (5-8 minute walk from the metro and train station to get pretty much anywhere - to the main attractions, Versailles(outside Paris) ,etc.) There are also two groceries that are a 1-2 minute walk away and many restaurants within less than a 5 minute walk away. I ran the Paris marathon and this was a perfect location - 17 minute walk to the Arc de Triomphe and the Champs-Élysées starting point.
