Amanda's place was wonderful for a long stay in Paris. The studio is located on the Left Bank, near numerous important metro stations (e.g. RER B Luxembourg and a 10-12 minute walk to the St Michel-Notre Dame metro) and is in fact walkable to the lower Marais on the Right Bank (~25 minutes). Skip the cafés on rue Soufflot; there are other excellent boulangeries/cafés/bistros on smaller streets 5 minutes from the apartment. The studio is also a 10 minute walk to rue Mouffetard. If you are a student, there is a place where you can print nearby (Mistral Photo). All in all a perfect location.
Other notes:
-I was here in the summer, so it could get quite hot, but nothing that cracking both windows open won't fix.
-The stove is induction, so it heats up and cools down very quickly and only cooks at one heat.
-The bathroom mirror opens up into a cabinet.
-The shower door can double as a full-length mirror! ;P
-I would not recommend this place for anyone above average height (especially if you plan on washing dishes), given the slanted rooftop ceiling.
-The windows open onto a phenomenal head-on view of the Panthéon.
-You will have to purchase your own toilet paper.
-The elevator stops in between the European 5th and the 6th floors, and you walk up to the European 7th floor, which is to say that the studio is actually on an American 8th floor.
-The washing machine automatically goes into dryer mode unless you stop it, so take care that your clothes won't shrink!
