The apartment is as advertised, however with property there is one mantra: "location, location, location!".
The apartment is 90m from Hotel de Ville metro station very easy to get to! 500 m from Cattelette RER station (we were there at rush hour and decided to walk with kids and luggage, no problem). It also is walking distance to the Louvre and Notre Damme (500m - perfect for evening bottle of wine and sunset!).
Definitely recommended!
