Nobody got the correct answer from my contribution a couple weeks ago, but if they had put the cursor over the pic they would have seen it was Plovdiv, Bulgaria. The signpost translated to Maritsa which is the river that runs through the city.
Perhaps a bit easier:
1. It is the UK
2. Multi-million £ mansions nearby are regularly bought then bulldozed to make way for bespoke rebuilds.
3. This property, which has no utilities, recently sold for nearly £200,000. Plus you're not allowed to live in it permanently.
4. Aficionado's of Bob Carolgees will have half the answer. (UK members clue)
5. A rather large river has a cake named after it plus an ex. President (US members clue)
Can you name it's exact location.
It' view
Well had to spice it up a bit
