Cozy and compact suite in a great part of town that was close enough to the action, transit accessible, but quiet at night, Yves' place was a wonderful base of operations for my stay in Paris.
The view is breathtaking, and the amenities were fantastic (power blackout shutters, air conditioning, dishwasher, washing machine, a full collection of Tin Tin comics). The sofa bed was firm and comfortable too.
Note that the unit is small, so two big suitcases will fill up the space quite a bit.
The building itself is quiet, and the elevator is a big bonus!
