The apartment is beautifully decorated and very cozy. It was clean and well stocked with linens. Our group was composed of two adults and two young kids older than 5.
The kitchen has all the necessary appliances, the sofa bed is comfortable and easy to open and close. The stairs between the two levels do not have a railing so I would not recommend the apartment for toddlers.
Lastly, as described, the apartment is very close to the Odeon metro and situated on a famous little street making it ideal to watch the people walk by.
