Fantastic neighborhood and the host is terrific. He waited for us even though we were 2 hours late and then gave us a great tour of the neighborhood. The neighborhood is wonderful and we loved all the great restaurants, pastry shops, beautiful buildings and being near everywhere we wanted to go. It is a five minute walk from the louvre, Norte dame, the seine etc.
There are a few things to be aware of. The apartment has no air conditioning. We were in paris during a heat wave, 100 Fahrenheit, 40 Celsius, so that was a little uncomfortable. One of the beds is a sofa bed and may not be good for people with back problems. There is a washer but no dryer. The ceilings in the showers are very low and there is just a wand you have to hold to use the shower. You cannot place the wand anywhere so the water comes down over you.
