My 17 year old daughter and I have just returned from Paris and can highly recommend Elodie's apartment. We took the direct Roissy bus from CDG airport which stops about 5+ minutes walk from the flat, so no trundling suitcases up and down Metro steps. The nearest Metro is a stone's throw away, making all the sights easily accessible and as the property is surrounded by many restaurants it's an ideal location. We took a last minute decision to attend the France vs Scotland rugby match; 2 train rides and we were at the Stade de France in under 30 minutes!
The flat was cosy and although temperatures were hovering around 1 degree, it warmed up very quickly.
I would agree the lift and neighbours can be noisy Monday to Saturday between 8-8.30am, but we were surfacing around then so it wasn't a huge inconvenience. If you're a late sleeper it might be more irritating. We shared the king sized bed and we both commented on how comfortable we found it, I suppose it comes down to personal preference. Elodie was really helpful and quick to answer any questions we had. A comfortable, well equipped flat with secure entry - would recommend!
