Longguang's place is a good value and the location is perfect if you're trying to hop on one of the hop on/hop off bus services or grab the metro. It was down the street from the Louvre, which comes in handy when you take a cab, as you can easily navigate to the location once you approach the museum. A great place for our 3 night stay and communication was great via messaging through Air BnB.
It has the basics including a hair-dryer, instant coffee, towels and linens. He also provided lots of bottled water, which was greatly appreciated! At the time of our stay, the shower head, though it was a handheld shower wand, wasn't fixed to the wall, making it a bit difficult to wash your hair and the shower door was a bit tricky. I'd suggest this place for intermediate travelers who know they are going to spend most of their day out touring. It may be considered a bit lackluster for those traveling to Paris for the first time or for those who enjoy creature comforts on trips. We were 3 American travelers; all extensive travelers but one person's first time in EU.
