Alex's apartment is exactly as shown. The wall to ceiling windows are lovely as is the open floor plan. It was in the perfect location for us. It's incredibly walkable and there are two metro stops nearby. There are three staircases, so be aware! For us, the lack of privacy (no door to the bedroom, and large glass door to bathroom) wasn't an issue and it was the perfect modern home in Paris.
Yes, the show stall has some stains and needs some new grouting put in, but the rest of the apartment is lovely. We really enjoyed our stay.
