Hard without knowing the style of your apartment. My personal preference is the bottom pic (with flowers). I love the ledge for displaying ornaments and a statement mirror or artwork hung above.

i love the pictures that Siriuskey has posted (this site is so frustrating in that you cannot reply to other users!!), the stone work is fabulous - and window seats would complete the cosy, ski lodge feel - but those TVs are so high up! I am Not a fan of tvs over fireplaces, especially with such a spectacular architectural opportunity on the wall behind it. it is possible to get artworks positioned on a track to cover the tv if there is not another possible location for it. just a thought!

depending on the size of the room i would add a wall of high and low, closed and open bookshelves on both side of the fireplace but difficult to be specific without a plan showing size of the room and location of doors, windows and names of adjoining spaces

The second look like they are designed for stairwells so I'd be a bit wary about using them up higher as the light might be a bit "spotlight" and not diffuse enough. I think both styles work with your house design
