It’s usually easy to tell when a home is really just a market opportunity, rented out to make profit for landlords. Similarly, it’s easy to tell when a place has actually been lived in, as is the case with Fibonacci. There are books on the shelves and things in the cupboards, and it’s touches like this that give a flat a soul (although the less said about the motivational quotes the better). A split over two floors helps as well, but because the stairs are quite steep, small children have a difficult time reaching the bedrooms, so we’d probably suggest a minimum age of five or so.
