[Best for one person] It is located in 16th district which is a super safe quartier. Just 5 metro staions to eiffel tower. Park Boulogne and marmottan monet museum is near also. But its really small(11m) located 6th floor. And no wifi!
*one important thing to know: you can use hot water only for 15 minutes in a row. So when you take a shower, don't let the water coming out continuously.
No wifi and it is 11m(size) at 6th floor
