Vivaldi rooms are operated by Hotel Mozart. 7~10 min walk to the metro. The area is filled with the little stores and restaurants. But from the airport, you will need to use the taxi 45min. at fixed rate of 48 euro. No train access really. The check-in was at Hotel Mozart. We were traveling with 3 large check-in bags and 4 carry-ons. it was just hard to drag our bags to the check-in desk. We had to drag our bags back to where our taxi dropped us. Pros: Rooms are tall, hence perceived large, The view from 4th floor to Corso street is great. AC works, just set it at 22~24C. The bathroom was large with the shower booth. The breakfast-above average. The morning staff are pleasant. The location is superb. Cons : They do not have on-site concierge service, although the hotel Mozart staff was available on the phone during the day. The communal door was left open, no attention given, until we got home to close it ourselves. Nobody picked up the phone when we tried to report this incident. A sour smell from the AC unit, until AC starts again. The breakfast selections, although delicious, the focus is more on the sweet bakery goods. They need more original warm breakfast options. One bellboy cannot handle our bags to our room and we were dragging them together. Helpless. They should provide the cart for guest check in/out. Overall, our stay was interestingly very satisfying. Perhaps, because I had already accepted that it is more of the serviced apartment. But, pleasant after all.
