This is definitely a wonderful apartment with great hosts! Check-in procedure was easy and even if it required a quick step-in to Saint Shermin to get a key, it all went smoothly. Apartment itself is big, very clean with great interior and good facilities, high ceilings and lots of space. Location was also good for us: we enjoyed several walks from opera-houses and MuseumsQuartier (ca 15-20 min). Communication with Sabine and Kurt was fast and clear, they were very helpful and hospitable. Apartment is suitable for a couple, travelling friends or a family. We would definitely recommend this to our friends or anyone who are planning a trip to Vienna and need a great place to stay! Greetings from Estonia! Helena and Suivi
