We stayed here for 4 days and we couldn’t be happier with everything! The staff is great with communication and they were able to answer all of our questions very quickly via WhatsApp. They are easily reachable and eager to help with anything that we needed. The apartment was very clean and the rooms were a great size. The location is great! Walking distance to shops and cafes and to public transportation. I will definitely be staying here again on my next trip to Vienna!
