Pros: The apartment was perfectly clean and well apportioned. Anything we needed for our stay was there. We had the wrong street address (our fault) and the property manager, Nimpha, kindly came and collected us. She gave us a great overview and explained everything very well. The property is located quite near the Bastille Metro station, which was very convenient.
Cons: The apartment was VERY noisy. The windows overlook an alley that has a dance hall/event venue. The apartment literally shares a wall with a dance club. People queue up every late afternoon and there are many people outside the window, increasingly drunk through the evening. It never stopped before 1 am and Friday and Saturday went on to 4 am. Keeping the windows closed helped somewhat, but the apartment was warm for us and we were unable to turn the heat down. "Zenitude" is not the word... it's more like "When-are-they-going-to-stopittude?" The entrance is not on the alley, but the street it is on has about a dozen bars from the door to the corner, about a half block. We had no problem, but it was awash with inebriated people every night, again especially Friday and Saturday. Also, if you charge to use what's in the apartment (like coffee), it is not 'for your convenience.
Overall, a nice place to stay, especially if you are a party animal. If you prefer to sleep in the dark hours, keep looking.
