I've lived in one before. It is definitely a significant inconvenience. Some examples: - I biked to work. Carrying my bike up 5 stories of narrow stairs, bumping into everything, every evening was not a fun way to end my day. - Moving any heavy/bulky object will make even paid movers cry. - It makes coming and going feel like a sizable task. That said, I still preferred it over a lower floor, because it meant no noise from above and less street noise.
