Location wise - Superb near the train stations and restaurants/ grocery. However the unit is located in the 2nd flr (0 as ground flr) so ensure you don't have big and heavy luggages..
Bathroom - shower area is a bit small, you can only change clothes outside.
Cooking Area - there's no Range hood, thus if you fry something or with smoke it will be smelly for the whole room.
There's a washing machine , but no english instructions how to use it.
But overall its a good unit if you want to be near the Eiffel Tower and central Paris.. the Host is super responsive as well and considerate. :)
