I stayed in this apartment April 5th-10th. It's in a great location in the Marais. It's on a quiet street in a busy area. It's convenient to several metro lines and easy to get around from.
The apartment is very true to the pictures shown. I have to agree with the previous poster who said that the bed could have been a little more comfortable. It wasn't terrible but a new mattress and more comfortable pillows would make a great difference!
Check in was easy and the host was there exactly at noon. He showed me the apartment gave me an overview of the TV and washer/dryer the apartment in general and left. It was a great experience. He also answered the phone immediately later that day when I had a question.
I would definitely stay in the apartment again!
