We've spent a night in Michael's place. Everything is top-notch. The apartment was recently renovated and all appliances are brand new and of high quality. The apartment was perfectly clean. Communication was good, we've received clear instructions on how to get in. We've also had breakfast goodies waiting for us. Ela, the local manager, was helpful and very courteous. The location is well situated, 300 m from the U-bahn station Längenfeldgasse, with a Penny Market supermarket located just across the street. The surrounding area is quiet. We will definitely stay at Michael's place if ever visit Vienna again. Thank you!
