We had a wonderful stay in this apartment.
The directions to the apartment from the airport were perfect (one train line) and it was very easy finding the apartment.
This is a beautiful apartment. It had everything you could need and was a perfect base for our family of four while in Paris.
The beds were comfy and it was nice staying in a residential setting.
Rue Montorgueil is a perfect place to see the best of Paris. All the reviews previously are right - this is a special street and the apartment is perfectly located to get the best of it. Especially important if you plan to be in Paris on a Sunday; as the street is bustling whereas most of Paris is shut down.
Really couldn't fault this apartment at all. We were weighing up it and somewhere in the Marais, but this street is so special we're glad with our choice.
