We rented both of Lincoln's units for 5 women. They are tiny but we were expecting that. The biggest issue was luggage - there really isn't anywhere to unpack your things and stow your luggage. Pack light!
Great location, close to everything, but very expensive. There is a great grocery store nearby so take advantage and buy light meals and snacks.
The futon beds are not very comfortable but after all of the walking you will end up doing in Paris you will be too exhausted to care!
We were never able to get the dry feature to work on either washing machine but made due with hangers on the railings.
Overall good place to stay.
