Isabelle's flat is located just next to some of the most visited places of Paris such as the Seine river islands including Nôtre Dame de Paris and Sainte Chapel, Le Marais and Quartier Latin. You will find several restaurants and coffees nearby and other parts of Paris are easy to reach with the metro which has several stations nearby.
Isabelle couldn't welcome us directly but everything was perfectly organized so we could gain access to the flat without trouble. A day later she met us and gives us some tipps. Generally communication was great with brief answers within a couple of minutes.
The flat it self was spacious with a well-stuffed kitchen, huge living and bedrooms and a modern bathroom with separate toilets. The bed was comfortable and everything was clean. Furthermore there was a fast wireless connection.
The only negative thing was that bedroom was situated next with poorly isolated windows. We noted the noise of the traffic during day but weren't really harassed and had no problems during nighttime.
All in all I could highly recommend isabelle and her flat as a nice and spacious hide-away from the rush of the city even if it's located in walkable distance to a lot of highlights and must-sees.
