1. the best location - There is an airport bus 'direct 2' stop right in front of the apartment, so you can easily come and go from the airport. Also, the place is just 5 minutes away from the Eiffel tower. You would frequently meet the Eiffel tower while you are outside around the apartment.
2. the condition of the space - the host had prepared his apartment to be clean before I arrived. Everything was clean and good.
3. the host's attitude - David was a great host. I could not meet him in person, but we messaged or made a phone call to each other with whatsapp to communicate with any issue I had. He speaks English very well, so I had no problem to communicate with him. He also treated me so kind, so he gave me another good impression of Paris, France too.
