Hi @GosiaAr welcome to YogaForums
I have had great experiences travelling and visiting local studios although mostly across Asia, Australia and the US.
I have noticed that each region has a different style and flow. Even east and west coast America had different vibes.
And the language barrier I think just makes things more interesting.
Are all studios traveller friendly? I couldn't see why not. If they have drop-in pricing then have a go.
Also a nice way to meet locals and ask a few questions about where like minded people might eat dinner, enjoy nightlife or spend a relaxing day.
Good luck, hope you have a successful trip!
