A simple apartment, like a small hotel room, but has all the basics for 1 person. Of course, you can't expect a Hilton for this price in such great location - you have everything nearby and a lot of sightseeing spots just a walking distance away.
The host is helpful and communication was easy. I'm glad this apartment was available on my dates - this allowed me to spend more time in the city center of Paris and get a better feeling of it.
