The property is excellent for a small family. It's pretty compact, but has everything you need in between exploring the old town or swimming at the beach.
The apartment was squeaky clean, and the bed was very good to sleep in. Also a baby cot was provided, and our baby also slept very well.
The host was super friendly and helpful. Check-in and out times were very flexible - of course we were also lucky that no-one was there directly before or after us, but still, it's not something I take for granted.
The only negative thing I can think of is that the air was quite moist, so it was a bit hard to dry swim wear and baby clothes, but that's probably a general thing in Split/other cities by the sea. There's also an AC unit that helped a bit when set to drying mode.
