The host met us promptly outside of the building and made us feel welcome. He showed us the flat and explained important information like phone numbers and where to take our rubbish. The flat was on the fourth floor but was no issue for us. The flat was in an excellent location, central yet quiet. The metro was very near. The flat was very clean with a nice bathroom, we had no complaints. We didn't use the kitchen as we always ate out. The sofa bed creaked every time we moved which was far from ideal. We then placed the mattress on the floor for the next few nights and slept well. Over all we were happy with our experience and would recommend this flat as a base to explore Paris.
