Really enjoyed our weekend stay in Armelle's apartment. It's in a good location 20 mins or so on the metro from many of Paris's attractions. Armelle was a great host - she made sure we had everything we needed and responded to our questions quickly. The apartment itself is stylish and comfortable, though the staircase up to the bedroom is quite steep so you'll need to be reasonably agile. The broadband is plenty fast enough for streaming etc.
Overall a good base for a trip to Paris and I'd definitely recommend.
