Yes I believe Portugals and Croatias stories are very similar, your capital being a coastal city probably makes it even worse with regards to tourist inflation.

Unfortunally tourist inflation, digital nomads, and foreign pensionists have driven house prices sky high, prevented the usual system of house renting for university students and people unable to buy houses, with crazy rents, as landlords rather profit from foreigners, thus that is how we end with a mostly right goverment, the far right having a large majority, with my parents and many others having fought the dictatorship for nothing.

Zagreb isn't a coastal city.
