Sure. My first tip, albeit obvious, is to thoroughly research the conditions in the respective country's public transport system with regard to costs. Many mobility companies offer special discounted tickets for frequent travellers or for special regions, so think in advance about which one is best for you.

There are different services, mostly apps, that can help you find an accomodation apart from expensive hotels (like 'hospitality networks') or rides ('mobility as a service' or 'ride-hailing' services). I find it difficult to give concrete examples because the same services are not available in all countries.

There are a lot of potential locations that may meet the requirements. As a general rule, it is wise to choose a spot that is a bit outside of big tourist hot spots and big cities. 'Exciting', of course, is also subjective.
