This is a great place to stay. You are a very short walk from all the great tourist locations in Vienna, but also in the middle of a wonderful, vibrant neighborhood with its own unique flavor and interesting shops and restaurants. Vibrant night life, beautiful views of the canal, and easy walking distance from the cathedral, the metro, the outdoor market, the prater fair, and many other great things Vienna has to offer. Ari was great too, very easy to get in touch with.
I would warn, this is a location in the midst of some great night life, including music venues and hoppin bars, which is definitely a plus, but it does mean it isn't the quietest if you are wanting to go to bed early. But it's more fun to go out and experience the night life anyway!
Great, clean, lovely apartment in a perfect, vibrant, safe location with quick foot access to so many things this great city has to offer. Definitely recommend to anyone.
