Our stay was seamless. Maria and I arranged a time to hand over keys/check in a couple of days before we arrived in Paris. This allowed a smooth and easy check in which meant we did not have to stress. Maria showed us around the apartment and explained how to use appliances and facilities. This was most helpful.
The location is excellent for shopping and just around the corner from the Arc de Triomphe.
We like walking which meant that we did not make use of the metro for any other landmark we visited e.g Eiffel Tower. I believe the furthest we walked to any of these was around an hour or a little more so easily accessible. Of course if you do not like walking then the metro and taxis can be of use.
Overall our stay was fantastic, Maria was a wonderful host providing a stay in a very nice part of Paris.
