We had a great experience and would definitely come back to this apartment.

The great: location, views, size (for a couple), luminosity.
The good: charm, decoration, equipment, cleanliness.
The not so good: first impression outside and inside the building, electric water heater slightly smaller than ideal.

Details:
Our cab driver got a little bit confused with the street address (just tell them "Pont Neuf, Ile de la Cité", it's really only a few steps away from the bridge) but we got there on time.

After a phone call, we were met by David, Evangeline's husband, at the door of the building. He was waiting fpr us at the apartment, making sure everything was perfect.

At first, we were a little bit scared because of the large scaffoldings covering the building's entrance, but fortunately they were there for the renovation of the building next door, and did not interfere at all with the view or the luminosity of the apartment, which were just as described and as depicted on the photos. The view is just amazing, you can spend hours by the windows looking at the bateaux-mouches go by, enjoy the sunset over the Seine, watching the people go by...

The location of the apartment is just perfect. You can walk to the Louvre, to Saint Michel, to Saint Germain, and of course to Notre Dame or Ile Saint Louis. Marché Buci is quite near, maybe not for everyday shopping but convenient enough to stock up the fridge.

Double height confers nobility to the interior, which is decorated with charm. There were a few extra goodies on top of those in the description, such as hair dryer, slippers, fairly complete kitchen equipment, among others. Closets are large and there is storage space, so our luggage was conveniently not in sight. Everything worked just fine, as described by David. The dishwasher was a little bit noisy (but that just meant you had to turn it on when leaving the apartment during the day) and the electric water heater fairly small (so we had to be careful when showering in order not to run out of hot water, nothing terrible, but if there are more than two people that might become an issue).

Everything went perfect during our stay. We had fantastic weather and enjoyed our holidays very much. We even invited some friends, as there is enough space to hold a small dinner or cheese and wine tastings.

The only thing we didn't like was the fact that, just after stepping into the building, you come into the staircase, which is a little bit dark, rather tight (beware of large suitcases!), not in a very good state of conservation (paint falling apart on the walls, old carpet, etc), and the place where the trashcan is (a bit smelly, and the first thing you see). But then again, part of the charm comes from it being a very old building, and all of this is quickly forgotten when stepping inside the apartment!
