Very inspiring, I wish I could try something like that for a while. Question: do you still declare your income in your home country (Germany, I assume) or have you found a different solution?
Most countries have agreements to avoid double taxation, meaning you just declare the income in the home country, as long as you spend less then half a year in the other country. The agreements usually have some rules regarding which country counts as the home country if you e.g. own property in both of them.
