Thanks for the feedback. I might keep it for myself and build a site. I lived there for over 10 years and think I have good knowledge to make it work and generate income through advertisements. I see a lot of potential.
If you've never been to Prague I highly recommend it.
Oooo, pivo, da, budu, zaebis, davaj dva! (same in Russian).
But yes, the domain does not stand a chance in terms of resale value. Limited not only to Czech clients, but also to Prague ones. Extremely tiny, super narrow niche, will not meet enough demand to sell it well (unless you develop it well but that's the whole different story). I also think you can find better, more popular names on the same subject and develop that one then.
