I am from Makarska, finished my college in Zagreb and now live on Zagreb-Makarska relation. Started AIRBNB-ing in early 2013 so I like to think of myself as an early adopter, at least in Croatia. It is a great way of meeting people from all around the world.
So, feel free to ask me anything while you're in Makarska, I'll be happy to help you.
P.S. Some of these apartments are my uncle's or my cousin's apartments so I might not have the chance to meet you, but I am always here online for any questions.
