Constantin’s place is absolutely perfect for a trip with a small group of friends! The apartment was beautifully clean, modern interior with a rustic restored vibe, and had everything you need in a place. The hosts were very helpful and would text back immediately with any questions and left a nice guide in the apartment with multiple sets of keys for easy access and travel. It’s located right next to multiple public transportation areas and is a quick walk away from amazing sightseeing. Definitely recommend staying here if ever in Vienna!
