The hotel is about 20 minutes walk from the heart of Sofia. It's a large hotel with multiple lift lobbies and large meeting/ event rooms everywhere. The private spa and gym accessible with a fee is world class with a range of equipment and experiences that would shame most hotel spas in northern Europe. NYE dinner at the Vienna Restaurant was very well planned..They even had a crèche for younger children with games and activities organised all evening in a room next to the restaurant. Thoughtful. The rooms were clean and comfortable. Recommended, especially the spa. Only annoyance were the temperamental lifts and electronic room doors that didn't quite work. Overall, excellent stay. Recommended.
