Nicolas was away so we were welcomed by Elke. She contacted us a week before our stay and provided us with all the information we needed for arrival. She was very friendly and showed us where everything was. She also gave us many useful suggestions of markets and food places since that is one of our interest. Her recommendation to catch taxi to Gare de Lyon instead of metro was spot on and much appreciated.
We found the apartment comfortable and well equipped. Everything was clean and tidy. Although Elke gave us her contact info, there was absolutely no problems during our stay so we did not need to use it.
What we love most was the location. It is central to all the sights, metro/train and so many restaurants around our building.
The stairs were a good exercise as expected but we will able to manage even though we were not that fit. It make us feel less guilty after our wonderful meals eating out.
We highly recommend Nicolas' apartment for anyone visiting Paris.
