Location: at nights a bit busy, outgoing, but residential, calm, relaxed atmosphere on the street ; can see Tour Eiffel from the bedroom window. Two metro stops within 5-10 minutes by casual walk (and this way several metro lines too). Easy to reach almost any place in the centre of Paris within about 30 minutes by public transport. About 2-3 patisseries/boulangeries very near, a boucherie too, and a major mall (with a useful huge supermarket) within short walking distance.
Host: thoughtful, caring, friendly, cheerful. Let me use the kitchen and at times offered me a meal too. Helped me with transport and touristy & local advice, walked with me to the metro stop and helped me buy my weekly pass there. I enjoyed my chats with her daughter as well. In sum, I really loved my stay!
Apartment and room: clean, stylish, homey. There's quite a library in the room too. Refreshments (crisps, mineral water, sweets) waited for me in the room when I arrived! There was also a good set of useful essentials just for me (besides towels, tooth paste, shampoo, hand cream, shower gel, earplugs, etc).   In sum, I very much recommend Lili’s place! : )
