Antonin's place was perfect for 2 people staying a few days. Be sure to pack light, because you're gonna have to walk 6 flights of stairs! Gare du nord & gare de l'est were very much close by, so with train it's so easy to access his place. There aren't much parking places nearby (read: any), so that's something to take in consideration if you're going to go by car. The neighbourhood is nice, so many restaurants nearby, little hipster neighbourhood. The only thing that i would not recommend is visiting with 2 girls, because in the big street next to the house there are a lot of gatherings of large groups of men. It can feel unsafe for two women.
