I didn't have the pleasure to meet Marie but she was friendly, helpful and her instructions were clear and easy to follow.
Despite the cute design, the flat was freezing cold and there was no proper heating system. I grew up in Canada and I'm used to cold temperatures but this was too much.
The 5 blankets she left on my bed weren't enough to keep warm.
Plus, the shower had exactly 7 minutes of hot water.
Please avoid during winter unless you're looking for a post-world war 2 experience.
A part from that the location is perfect.
Unfortunately I wouldn't recommend it till she gets a basic thermostat. I didn't know "heating" was a luxury in 2015, mostly in the hipster neighbourhood of Le Marais.
