We had a great stay in Marcus's apartment. The place is lovely and cozy, with tasteful decor (we loved the antique cupboard and stove!), very clean and impeccably well appointed: dishwasher and washing machine are a definite plus and the espresso capsules + welcome chocolates a great touch!
Best of all the apartment is located on a quiet street and that, combined with the good quality bedding, meant we had 2 great nights sleep.
It was very warm in Vienna on the last weekend in August but thanks to the high ceilings and great insulation the flat was deliciously cool.
we didn't meet Marcus personally, but we had a super smooth experience in communicating, picking up and dropping off the keys eyc.
All in all a great experience, would definitely recommend!
