If you are in Paris for sightseeing then definitely consider this place to stay. Location is perfect and everything is within walking distance - there are good shops with cheese and wines, groceries if you need, parallel street if full of restaurants and cafes, all main sightseeing places are 1-2km walking distance (though I was still using hop on/off bus to get to few other places).
Another great thing you get is WiFi 4g key which you can always have with you and stay online.
Alexandre is quite responsive and hospital so any questions raised were solved or relied same day!
Have a nice Paris trip!
P.S. Book your visits in advance online to skip long tickets lines and buy museum pass if you plan to attend a lot of places.
