I had a lovely stay at Martine & Karim's place. The studio has everything you could possibly need: shampoo/shower gel, cleansing water and cotton wool, towels, hair dryer, kettle, coffee machine, stove, fridge, a comfortable bed, WiFi. The hosts left some orange juice, milk, water, fruit, tea, coffee and cake for me to have during my stay. Before I arrived they contacted me to tell me about which trains/metros to get from the airport (the metro stop is less than 5 minutes walk away from the studio). Overall, a lovely stress-free stay in Paris!
