Staying at Beata's apartment was the best choice we could have made. Mr. Popus was very kind and helpful, answering promptly to our questions and needs. He was waiting at the apartment with the keys when we got there. The apartment is very cozy and quiet, perfect for staying near the city center and for walk tours. We only used the subway when we went to Schonbrunn palace. There's plenty of cafes, restaurants and supermarkets nearby. Very good location!
