Location was good and I and my friend (we are 2 women in our 50's felt safe). Supermarket and restaurants nearby and the metro a 8-minute walk. Once in the flat, it was very quiet except for the child upstairs who was jumping on the floor until after midnight most nights and crying in the morning. The flat was small, but just fine for Paris and certainly for the price.
We arrived an hour early due to an unexpectedly quick taxi ride and the owners met us about 10 minutes late which was understandable. They were very warm and welcoming, but clearly not prepared for us, and I don't think an hour later would have made any real difference. The husband showed us around while his wife talked on the phone and worked on her computer. The apartment was not ready for us and so my friend and I went for an hour lunch with their assurances that the apt. would be ready and they would be gone when we returned. The opposite was true! When we got back, the flat was not prepared and they had another woman there and had obviously eaten a meal. We just stood there while they scurried around making the beds and cleaned up. It was very uncomfortable and awkward. We never felt that the place was very clean. One roll of toilet paper & a half a bottle of dish soap that was clearly half water. Just to be clear, I have traveled extensively in many developing countries and don't think I am all that demanding. I would not recommend this apartment. This is my first experience with Airbnb and it makes me reluctant to give them another chance.
