An Excellent physiotherapist for poor posture in Budapest/Vienna/Barcelona?

Hi, I'll be visiting Budapest, Vienna and Barcelona for a few days each and I'm looking for a really good physiotherapist who specializes in posture and musculoskeletal issues. Someone who can help me find the root cause of my posture related issues.

Since I'm only passing through, I'd ideally need someone who can provide a useful assessment and advice in a single session. Is that realistic?

Any recommendations for someone skilled and reasonably priced would be greatly appreciated. Thanks!
