What a lovely room. From personal experience I would avoid wall to wall carpet if you intend keeping any furred pets or have children (we have 4 of the former and 5 of the latter!). Hard floors are much easier to keep clean, much better for people with allergies and in my opinion look a lot more elegant than fitted carpets. We have very little fitted carpet in our home, only in a dressing room and two of the bedrooms (one of which is now our studio space, so the carpet will be going from there in the near future).
We have polished wooden floorboards with pure wool rugs of various sizes. The rugs can be taken out for a beating/airing and when they get worn are much cheaper to replace than re-carpeting. It also makes re-decorating an easy thing....you can inject a splash of a new colour, just by choosing a new rug.
Hope you enjoy your new home and have many happy years there.
