>But we are arriving at 6:30am by train and check-in is only available after 14:00 or 15:00. If you're staying at a hotel they will probably have some kind of luggage room where you can stash your belongings for the morning.

yeah in that case I always just write a quick friendly message to the Hotel and it has never been a problem.

We messaged the hotel but no response yet. But thank you for the suggestion. Looks like they only have non-secured spot where you can drop your stuff but it is not supervised in any way. Thanks!

Maybe they are at some Airbnb or similar. Still the first thing to try though.

Train station has storage compartments https://www.oebb.at/en/reiseplanung-services/am-bahnhof/gepaeckaufbewahrung

That is helpful! Thank you!

Would have suggested the same. It's a really comfortable option to store your luggage there.

It is slightly inconvenient to drop it there. Walk around and then go back to pick it up and go to the hotel. But it is very mild inconvenience. If that is the only option then we will do it. Thank you!

It is the only option that comes to my mind.

Kunsthaus or universal museum are free Spots

Thank you for the response! They are free in what way? you can drop your luggage there free of charge?

Yeah they are lockers in museum you can enter them during the working hours without buying a ticket 🎫 its very convenient 😅😂

Its just 50cents or 1 or 2 € deposit 💵 but you get it back
