I'd return to Christian's apartment in a heartbeat!

Pros: 1. Amazing location. Right near Notre Dame and Latin Quarter, which translate to amazing choice of restaurants, bars, shops, and clubs. Everything, except perhaps Eiffel Tower for some, is within walking distance. 2. Christian. This guy knows how to treat out-of-town guests. He was there at 11pm to let us in. Two binders full of tips. He even let us store luggage until our evening departure and that made logistics so much easier for us. Super-fast internet. Eclectic/abundant amenities in apartment. Two thumbs up, way up!

Cons: I can't really think of anything. Perhaps a negative if you don't wanna be where the action is?

I only wish I can go back to Christian's apartment soon enough.
