Right now I live in the city center of a medium size city, where I do not require a car, can walk to most important places, and cycle to work within 10 minutes. To the opposite of my appartment is a medium size bar, which funnily does not cause any trouble, not even at bigger dance parties at the weekend. The train connection here brings me within 30 minutes to the 2 biggest cities in the country, where I can easily access what I don't have in the city itself.
The city itself could be a tad bit bigger, but otherwise it's quite optimal, I would say. The features mentioned are quite important (medium to big size, but everything easily available).
I live in an appartment in a house with 5 other parties. My appartment is a tad bit small, so for a realistic option I'd like to have 5-10 sqm more, and some storage space/basement, but also here, otherwise it's what I need.
If I had endless money though, I'd go nuts. Not sure if I'd like to have a villa, but in my massive garden, I'd like to have a fake Greek temple like the one in Schönbrunn castle (this one
