I stayed at Juan-Golan's place on a long stay, for 2 weeks. The house has everything you need to make quick meals, store food, and feel comfortable, and safe. The house is in a very lively location, but as the room I stayed in faces the back of the building it was very quiet and calm. The internet connection was good to make zoom calls and streaming.
Juan-Golan is very friendly and helpful, he shared the best bakeries and restaurants to go to.
The building is also safe and quiet and steps away from multiple supermarkets, restaurants, bakeries, metro stations, and walking distance (14 min) to Gare du Nord.
