My husband and I stayed in Christophe's place for nearly a month, and had a perfect stay! Check in was completely painless - Christophe's neighbour Tatiana let us in, and gave us a great welcome - she's lovely! Christophe had given us a very comprehensive guide to the apartment, which made everything so easy. Check-out was equally pleasant - we got the pleasure of meeting Christophe, and having a very lovely chat with him before leaving.
The apartment itself has everything you would need, and is very comfortable. The decor is also really homey and interesting. Oh, and bonus dishwasher! A real rarity in Europe! The wifi also works well.
The neighbourhood is perfect. Republique is less than 5 minutes away and has all the metro lines you'd ever need. And it's a really easy walk straight to the river.
I would absolutely recommend Christophe's place if you're looking for an apartment in Paris. We'll probably stay there again ourselves! Thanks, Christophe!
