I stayed in Liliane's appartment for about 3 weeks and I can only recommend it to anyone visiting Paris. It's literally 5 minutes away from the tube station, there are shops and pharmacies around as well. Auteuil is a prime location, within Paris but also very quiet and secure. The appartment itself is cosy and homely with a very modern kitchen. Martine's daughter was very welcoming. I had an amazing stay and wouldn't hesitate to come back.
