The place is perfect for four persons, the furninshing is great and the flat is located near Bourse and Grand Boulevards subway stations.
Also with a 10-15 minutes walk you get to the Louvre Museum and the Beateau Bus stop.
Patricia also is a very precise host, she gave us all the instruction needed to get into the apartment and she has always replied quickly to any message we sent.
The only con I can find with this apartment is the very small bathroom which can be a problem if you have kids, we were four adults and that was no issue for me, also the shower is bigger enough to take a shower without problems.
Some nights the club downstair can make a very big noise but they always cut the music around midnight so we had no problem sleeping, but take into account that if you want to go to bed early you can have some problems falling asleep since the music is very loud.
I hope I can use this apartment next time I'll be in Paris too.
