Hans' apartment is located right by the Champs Elysees and it is just a wonderful apartment to stay in. It is the perfect size for two people, with enough room to roam around the studio. The kitchen is just the right size to cook a meal, the bathroom is nicely quaint and you have enough place to maneuver around it after you step out of the shower. The bed retracts from the wall and is incredibly comfortable to sleep in with luxurious down pillows.. You can always open the window to have fresh air and a view onto the street, which is not that busy. Sadly there was construction happening at the time of our stay but it did not take away from the fact that the apartment was truly amazing.
Hans himself was also a wonderful host who was helpful whenever we needed him.
If you plan on staying in Paris, consider this place because it will improve your stay there greatly.
