Matt, not sure how much two star places are these days, but the last time we went to Paris we decided to rent an apartment for a week - more room, a small kitchen with 'fridge to store some wine and cheese, etc. We rented from Paris Vacation Apartments
, and wanted simple/inexpensive and got a studio in Montmarte, with a great view of Sacre Couer. It was great to go to the market for food, with the apartment we didn't have to eat out every night. The apartment was a 5 min walk from the Abbesses metro stop. The only minor disappointment was the bed - a kind of matress on the floor - but that was the only apartment available when we booked, and we went on a whim, with less than a week's notice. Service from Isis was excellent - she suggested local bistros, arranged taxis, made reservations at the Big Name restaurants at which we needed, er, wanted to eat...and just as important told us the places to avoid. She speaks flawless English.
