Stockholm Globen (now Avicii) has been one of my fave arenas so far. Espoo is nice too. On the other hand, Palavela in Torino is certainly my least fave. The press room is ridiculously small and the press stands not much better. Medolanium Forum (Milano/Assago) is more comfortable although the arena is quite old. Accor Arena in Paris Bercy is perfect but it's no longer used for FS events (too expensive) but we have Aren'Ice in Cergy, not far from Paris, which is brand new and superb. Angers Arena is great too. Grenoble Polesud is average. The arena in Kaunas (Lituania) was good too and so is Tondibara Ice Hall in Tallinn (except for its outside architecture as I'm not at all into brutalism.) Centre Bell in Montreal is beautifully located downtown but not very practical when you work as the press room is on the top floor and the press stands 2 or 3 floors lower with slow and crowded elevators. Sofia (Bulgarie) and Debrecen (Hungary) have old decrepit arenas with very uncomfortable seats. I've been to countless others in Europe, NA and Asia but I can't think of any particular ones either in a really positive or negative sense.
