The host: Jerome was a welcoming and generous host who greeted us with cold drinks and helped us get into the flat (we had suitcases and 2 kids)! He offered whatever was there to use, including coffee for the espresso machine, etc.
Pros: clean, spacious (we were 2 adults and 2 kids); clean WC with good water. Kitchen pans for stove top cooking and microwave, fridge/freezer. Wifi was the fastest I've seen. Safe and Secure - most important! 10 min stroll to the Louvre. Didn't need to use the metro
Cons: noise from adjacent streets and nearby bar, but this is downtown Paris. Closing the windows helped but we needed to keep them open a couple of nights during an early heat wave.
Summary: great - highly recommended!!
