For the way I travel, location is the most important aspect of a place to stay. This great apartment has that with Metro stops, RER, and the best walking take off point on the Left Bank.
The apartment is very roomy for Paris. My sister and I were travelling together. This place has not only separated nice beds and bedding, but separate rooms. It has everything you could possibly need in the way of kitchen equipment. Plus we lucked into a generous supply of fruit, juices, organic coffee, etc. The bathroom seemed new and spotless. The street has notable architecture. Luxembourg Gardens is right here!
I highly recommend this place.
