Really nice apartment and had everything we needed. A little far from the touristy parts of Paris though but the subway is close and an easy way to get around.
Grocery stores are steps away, washing machine, big fridge, easy self-check in, great price.. Negatives are traffic noise from the street and the appear to be a bit older than my impression from pictures with run down stairs and wooden windows.. After all it is an old apartment with new interior. But for the price I am very satisfied for what I experienced.
I had a great stay at Mercedes apt. She was very responsive, replied very fast, and even though we haven't met, she was very nice and polite. The check in and check out process was super easy. The apt is completely renovated, so everything is new, modern, charming and clean. The location is good, very close to two metro stops which take you everywhere in the city in few min. It can be somewhat noisy, but nothing that earplugs won't resolve. All in all, it's an amazing studio and definitely recommend it!
