We stayed here for 5 nights. Great location, great apartment. Room was clean & comfortable. Though we didn't see Cyril very much, he was nice & helpful. Everything you need is there, you only need to bring your toiletries really. It was a little uncomfortable when we had to walk pass him to go to bathroom in the middle of the night, but soon we learned if it didn't bother him, why should it bother us?
There's also a bakery that sells the best pastries in the whole of Paris (well...according to us anyway). So all in all we'd recommend Cyril's place to anyone :)
