I'm (31f) doing a 1-month solo Europe trip this fall - a bucket list item for me! Everything's refundable and I'm just crossing my fingers the world looks different by then and I'm vaccinated and I don't have to cancel!

I am sticking to a moderate budget, with some intentional splurges. Of the following places I'm going, in which cities am I just as well sticking to a hostel, and which cities are worth a (moderate) splurge stay? (For example, I think a room looking out on the Venice canals would be dope.)

Rome

Venice

Salzburg

Berlin

Amsterdam

Paris

Lisbon

Barcelona
