Marine's flat is beautiful and it was a very comfortable home for us when we were in Paris. The flat was even better than we anticipated from the pictures and there was a lot of space for my friends and I on our girl's trip to Paris. The 3 flights of stairs were only a challenge when we brought our suitcases in - otherwise it made us feel more like true Parisians (and helped work off some of the delicious bread we were eating!)
We had great communication with Marine before check in and there were lots of books and maps of Paris in the flat to help us with any questions on our trip. There was a lovely bottle of wine and breakfast stuff waiting for us when we checked in. The flat is also very close to the Metro - which was great for us as we were exploring the city.
I highly recommend Marine's flat if you are heading to Paris!
