Didn't meet Louise but met her mother Patricia who was lovely, and met us at the metro and then walked us to the apartment as I was unsure where to go and she spoke excellent English. She explained about different types of tube tickets we could get to help with the stay.
The location is great for independent bars and restaurants and boutique shops along the canal which offers lovely walks in the sunshine.
I visited with my daughter and felt safe at all times especially with two different security codes to the building. We didn't stay out past 10:30 so can't comment on the night life.
Gard du Nord which has the Eurostar line is only an 8 minute walk away so don't think you have to fly but if you so, Charles De Galle is super easy on the train, about 30 min direct train.
It's also a fantastic location to explore Paris from. Monmatre is a 25 minute walk and we were at the Arc de Triomphe within 30 mins on the metro which is super cheap (€1.90 each way)
