Well, I'm not helping by saying that Sofia ticks all of these. 
But also:
- rather smoggy during winter;
- currently has pro-russian government, Radev is like Orban from Temu;
- not very bike friendly;
- the house with the garden won't really be in the town
- coastal is 300km away (closest in Thessaloniki, Burgas is 360km away);
- 2k high inactive volcano bordering the city, but still a mountain.
