in a comment on another answer you mention:
I have two cities (Tallinn and Stockholm) scheduled in my Calendar for
the next one year in the ratio of 60 to 40. I think I should include
both in my address field. Now, I have it like Tallinn, Estonia.
Stockholm, Sweden. What do you think? - - To include only one city is
rough estimate. To include separate dates at each cities is too
cumbersome and should be left for the cover letter.
Your situation isn't standard. When people inquire about how much traveling a position requires they generally are talking about one of two things.
how often will I have to stay in another city overnight, and how long will the typical trip be in terms of number of nights? It is assumed and expected that all transportation, lodging and food will be covered. There may also be other perks such as extra vacation days. The question is usually asked when the employee has certain obligations that can only be done in the home city: family, school...
how often do I need to travel in the local region? these are day trips to meetings or customers. The amount of local travel and the typical locations can determine if a personal vehicle is needed, or one is provided, or if taxi/uber/public transportation will work. There is also an expectation for reimbursement.
You seem to be looking for either a job that will allow you to work remote or in multiple cities, or only part of the year in a specific city.
These are much harder to find. I wouldn't use the CV/resume to limit options. I would be only applying to positions where it appears there is the flexibility you desire.
Posting your CV with dates in each city on a job board will not work to only receive interest from places that meet your requirements. Many of the companies or recruiters will be scanning the words you write to see if you meet the minimum qualifications, they will either ignore your schedule, or decide it is not worth the effort to understand what you want to accomplish.
Use your resume/CV to convince them they should hire you. Don't use it give them reasons to reject you.
