The place is located close to Canal St. Martin and Republique Station.
Perfect in everything: very cosy, with a perfect Parisian atmosphere, and everything you need for a perfect stay. You got all the tools you may need in an apartment. The bed was very comfortable, the bathroom very modern with a nice Spanish shower, a wardrobe with hairdryer, towels, etc. The living room has a nice couch and beautiful details. I didn't find a plug in the bathroom (in case you may need it) or working lights on the ceilings, but other than that (which they are really minor details), the stay was as I expected it to be, and even better. Very bright apartment too with windows everywhere. It's a 4th floor, and most apartments in downtown Paris don't have an elevator so in case you can't or you don't want to do the stairs just keep this in mind.
I totally recommend this place for 1 or 2 people. Not just for the apartment, but also for the fast and detailed answers Clement gave me anytime I needed help. He was very nice throughout the whole journey, and ahead of it! 5 stars place! :)
