Klaus is a superb & knowledgeable host! He gave us a short introduction to Vienna & its history & the top places & restaurants to visit and interspersed with his interesting personal stories👍🏼 He also offered us food & drinks a few times and he has a rack of free food like cereals, biscuits, fresh milk, pasta, etc. Austria had a railway strike on the day we checked out & we couldn't travel to our next destination so he let us stay another night for free! Really appreciate your act of kindness & our small token of appreciation will hopefully adequately express our gratitude 🙏🏼 Have a great Christmas & a blessed 2023 ahead!
