I stayed in Ekaterina's apartment for 5 nights in Vienna, and it was a wonderful stay. The apartment itself is lovely and full of character; it is actually a loft apartment on the top floor of a hotel, with easy access via a lift and right in the heart of Vienna - St. Stephen's Cathedral is literally right on your doorstep! Yet the apartment itself was never noisy, and it is nice to feel safe arriving back at night because the shops and cafes nearby are all still open. And there is a metro station just a 5 minute walk away, which easily connects you to any other attractions or destinations around Vienna.
The home was comfortable, clean, and very well-equipped with items for cooking and laundry. The rooms are spacious, with comfortable beds. There was a good heating and cooling system, and the bathroom has two sinks, a shower area, and a bathtub. Ekaterina was also very kind and let us leave our bags in the apartment after checkout as our flight was only in the evening that day. She also responded fast to messages and made an effort to answer any questions we had. We loved staying in her apartment and would highly recommend it to anyone visiting Vienna!
