Simply amazing. Very well located in the heart of the Marais, this apartment has everything you need to be comfortable while staying in Paris and is walking distance to the river, Notre Dame, and the main metro station. I particularly liked the amount of effort the owners have put into providing you with useful info; things like where the local grocery store is etc, is easily at hand and very much appreciated.
The apartment itself is well equipped with everything you'll need if you're staying for a little or a long while. The owners were also very prompt to respond to all enquiries and v. Flexible with meeting times as well.
Highly recommended. I stayed for one month in June 2013.
