SO many! Things I have and love:
Inglenook fireplace
Hand painted antique Hungarian dresser base (folk art/floral)
Numerous antiques, all cheap and most rustic but much loved, including my Nan's Edwardian doll's pram and loads of beautiful hand-painted china.
Waaaayyyy too many books
Interior magazines by the hundred (a huge passion)
Character - my cottage is really small but looks similar to the one from The Holiday, it's really cute
Cherry blossom tree in the garden - the pink blossom is glorious
Things I love in others' houses and would adore in mine:
High ceilings
Lots of natural light
A garage for storage
Far reaching views
Outbuildings of any kind
Thatched roof (had this years ago, adored it, had to be sold in my divorce)
A spacious bedroom with room for wardrobes, or even a dressing room
A utility room
Boot/dog room
Symmetry
A staircase with banisters to decorate at Christmas, the kind you can sweep down in a Frock. Mine is typically cottagey, ineven steep, narrow and between walls with a door at the bottom)
A hallway (front door here opens straight into the living room)
Upstairs landing big enough for more than one person at a time and maybe a cupboard for storage
Spacious bathrooms
No damp/mould
Finally, one thing I had when we built a house years ago and genuinely miss: central vacuum system. It was absolutely awesome, if I ever built another house I'd 100% put one in again.
