Local media and information portals are very helpful for quick adaptation. For example, I recommend
https://burgasmedia.com/?lang=en, where you can find the latest news, advice for residents, reviews of local services, restaurants, and cultural events. This gives you a complete picture of city life: transportation routes, updates in medicine, programs for families, and leisure activities. Using such resources, you can immediately figure out what is important for life and what can be postponed until later, and it is much easier to integrate into the local community. This way, moving becomes less stressful and more comfortable.
