Jacques’ place is exactly as described on the site - the huge windows overlooking the canal is the real selling point for sure. I stayed by myself and felt super safe in the building - all my encounters with the tenants were both friendly and polite. The neighbourhood is a smorgasbord of nationalities, but again they were very kind to someone who is most obviously not local (try as you might, something will always give you away, like not knowing how to use the subway ticket machine). Just remember to leave the subway by the “rue de Flandre” exit - turn right at the top of the stairs and the entrance to the building is between the butcher and the grocer. Which means you’re no more than 10 feet away from anywhere you may want to go in Paris - easy peasy!
