this apartment is centrally located in a convenient spot in Paris but it is closer to the porte de st Denis and not exactly in the Marais. the neighborhood has its own charm but if you're looking for the lovely boutiques and the bustle of le Marais you need to walk a few blocks. The flat was otherwise as described. Be aware that the shower is very small and if staying for longer than three or four days the place may be a squeeze for more than four people. the bathroom stank of mold and the windows were filthy but otherwise the apartment was clean. we were taken aback by merveil's many additional rules and requests (no visitors at all even during the day without agreement in advance, external deposit system, sending pictures of all passports, sending a picture of the key returned at the end, a fee of 170 if key lost) all the rules felt like an additional hassle and added to a sense of unease in the stay. that said, overall it still provided an excellent base to see Paris.
