We weren't able to meet Gaelle but communication was great. She responded super quickly. We did exchange numbers however I never needed to call her.
Her apartment is in a great location and I highly recommend it: it is about a 2 minute walk from a metro stop and about a 5 minute walk to nearby restaurants.
I loved her apartment: it felt like home away from home. Gaelle was super sweet to leave my husband and I champagne which we opened on Christmas Eve.
Just a helpful tip: there are light switches near both doors for the corridor. My husband and I didn't realize until after a whole day of me using my cellphone as a flashlight.
