I stayed for a week at Séverine's place, and it was great. Séverine is super nice. She helped me check-in, and made sure that I felt at home. She also introduced me to a lot of interesting places in Paris and in France, we even had time for coffee together, and I really enjoyed chatting with her. The apartment itself was also great, it was clean, tidy and well equipped - just like in the ads. It also sits in a very convenient location - only 2 minutes walk to Metro 2 & 3. The area is safe and lively, there are many nice cafés, restaurants and supermarkets around. I would definitely recommend this place!
