Bilbao: 3 days in Bilbao- what are the best parts of the city?
How would you organize 3 days in Bilbao? Would you stay 2 days in Bilbao to visit what's really interesting about the city and then head to the beach or outside of Bilbao?
Paris: How many days do you recommend to see Paris?
At the very least a long weekend, but a week would be much better
Paris: 14 days in Paris OR 7 days - Paris and 7 days - Rome
I think you would have plenty of time to visit Paris in 14 days, relax and "live like a Parisian", but Rome is also very beautiful - but much more a city to visit than to really live in, if you ask me.
