We stayed 4 nights at Leon's apartment and had a fantastic time! Communication was extremly easy, check-in went smooth as did the check-out. The apartment is even prettier and roomier than the pictures convey. Decorated by people who truly love Vienna, there are plenty of recommendations for places to visit, cafés and restaurants on top of nice Vienna guide books for visitors to draw inspiration from. We also loved the beautifully selected furniture and large bathroom! It's also a quiet area, we could sleep with the windows open and when construction started a block away, we simply closed them and heard hardly anything. All in all a great stay, great value for your money! Highly recommend staying at Vienna Calling!
