I can highly recommend this apartment. Though it takes you around 10-15 minutes by bike to enter the very center of Paris (like Marais etc.), the apartment is located quite nicely around the Parc Butte-Chaumond.
Sandro is a perfect host. Though our flight was delayed and we arrived only after midnight, she stayed waiting and welcomed us warmly.
The apartment itself is well equipped and decorated fancily :)
