We had a great time with Elitza. The place is very close to public transportation, just half a block from the Porte Maillot station, exit (sortie 2). You come up stairs near a restaurant called Fuxia. It was very clean and nicely decorated. It’s a studio but we made it work. it was very hot when we stayed there and she gave us a fan. It is a great location for getting to all the top sites, Eiffel Tower, Lourve, Arc, Orssay, etc. it’s on metro line 1, yellow line. She left us some cookies and drinks when we arrived. Nice touch. She was very nice and came to check on us to make sure we were ok.
A few tips:
There is a great supermarket under the mall, that you can access from the metro when you exit or by entering the mall.
Plenty of food a few blocks away. We like La Madison. The Bakeries she recommends are great.
