We had a great time in Paris and really liked "our" little flat in Saint Georges. The neighborhood offers a lot of little shops, backerys, supermarkets, bar, clubs.....almost everything you could enjoy in Paris. The apartement itself is very cosy with a nice and sunny balcony on the 5th floor. Bathroom is small but that's pretty common for Paris.
Marine was really helpful and a great host.
Only thing that was not perfect was the lack of internet in the flat....
All together i would recommend Marine's flat.
