This is very nice appartment. Very clean, you have all what you need there. The room is small (that is typical for Parisian appartments) but the bathroom was of normal size - good suprise. :)
Gilles and Nathalie are very nice and tactful people. I spent a little time in the appartment as I came to Paris to meet some friends and to see the city, but I did some good shoping in the neighbourghood - there are some boutiques (quite expesnive), but along the canal one may find interesting and not very expensive shops.
5 min to metro, 15 min to Place de la Republique (where you have most of the lines).
Many restaurants, cafe and etc.
Gilles and Nathalie, meci beaucoup! :)
