Isabella was a great host, she always answers right away... On the day we arrived, she was not home, but she did let us know in advance and her son checked us in. They are very friendly and ready to help with anything. The apartment was very clean and the place was very cozy. The location is just great, very close to the shopping street and also 3 min walk from a bus station. We are definitely staying here again when we come back to Vienna. Thanks Isabella!
