One of the easiest ways to make an apartment or a house feel like a home is to style areas with things you love by grouping them together in a nice way. I do this on bookshelves, in the kitchen, on top of our piano, on top of our fireplace, etc. We spend a month or more every summer working in San Francisco. We're lucky enough to have rented the same home for years but it's still not our home. I always find a few tiny things I love that I can take back to New York and I'll display them on a table or a shelf somewhere. It always makes it feel a little more like home.
