Antoine was a great host. Very prompt, friendly and responsive communication. He gave us great recommendations for places to eat locally and booked a restaurant for our first night. He also let us have a late checkout which was really helpful.
The studio is in a fantastic location, close to Gare du Nord and in one of Paris' coolest spots. There are tons of cafes, bars and restaurants plus a mini supermarket on the doorstep. Plenty to see within walking distance. The studio is small but perfectly-formed - clean, tidy and well-equipped with a decent kitchen and very nice bathroom. Comfy bed too. Some nice extra touches included juice, water and coffee.
Be aware it's a ground floor apartment facing onto the street so you do get noise from passing traffic and people, even at nighttime. I recommend earplugs!
We had a great trip and hope to return!
