Adriana's place is a great place to sleep in Paris for 2 - we were there 10 nights and enjoyed every minute of it. It is small (this is noted in the description) and technically can sleep three but you are going to feel pretty cozy with just 2. The nicest amenity is the washing machine (small, but gets the job done) and drying rack. It was really nice to be able to do laundry "at home" without using the sink. The host was really responsive to us during check in (our flight to Paris was 4 hours late) and later in our visit when we had a couple of questions.
The location in Paris is fabulous - right near Luxembourg Gardens, close to the Metro and RER, close to Notre Dame and a 10-15 minute Metro ride gets you to the Eiffel Tower or the Arc de Triomphe. About 5 days into our visit we started planning our return!
