Laetitia's apartment is perfectly located, the train station is just outside the building and everything else (grocery stores, bars, restaurants) is in walking distance. The view from the balcony is unbelievable - day and night.
The apartment itself is really clean, there is a kitchen which is great so you don't always have to go to restaurants but can cook your own food and the bed which comes down from the ceiling is really cool, too.
Check-in was easy and check-out worked well too. We were even allowed to leave our bags in the apartment before we went to the airport so we didn't have to worry about the bags on our last day.
If I go back to Paris, I will definitely book this apartment again.
Thank you very much Laetitia!
