My wife and I stayed in Nicolas' apartment for almost 3 weeks in April. Nicolas was very helpful in meeting us on arrival and introducing the apartment to us.
We had a wonderful stay. The location and aspect of the apartment is ideal, so close to St Germain, the Louvre and the Marais as well as overlooking the Seine. Watching the passing parade sitting in the sun beside the open window in the afternoon was sublime.
Nicolas' artwork and furnishings were a delight and gave us joy every time we walked into the apartment. We greatly appreciated the ability to use his very well equipped kitchen and enjoyed the local cable TV as well as excellent WiFi facilities.
The apartment has some quirky attributes, such as internal steps required to deal with plumbing and building development staging over the centuries, which added to the authenticity of the experience.
Having a lift in the building was a great plus given the height of the apartment, the common spaces were well maintained and services such as garbage well managed.
Overall, a most enjoyable stay that more than met our already high expectations.
