Communication was the best I've ever had with a host. There were a few setbacks with our plane and we were originally going to be early, but then we were late, and Marco was patient and kind and fast to get back to us so that we could meet with him and check in without issue. He even helped with a package we ordered to make sure we got it, and had juice and water in the fridge for us when we arrived.
It isn't in his control, but we were lucky that our shared kitchen and living room quarters had guests that were friendly but private so that you felt at ease without hindrance. Overall I met 5 flatmates during our three day stay, and they all kept to themselves and were respectful of their volume during the night. We were lucky, but I'm sure that if you were being bothered by a flatmate's noise when sleeping, that Marco would be there to help you asap.
Everything was clean and comfortable. No bed bugs, no scary stains, and no foul smells. Everything was in working order and the wifi was fast. It's also very fun going through the buildings to get to your room, much age and rustic value in my opinion, though someone more persnickety would have found it not to their standards. I hope you find the beauty in the spiral staircase of old wood, it was a highlight!
Really, Paris wouldn't have been nearly as fun if we weren't staying where we were. There was no stress and it was an utter relief. Thank you, Marco and family!
