Panarea / Hotel Raya / Aeolian Islands Travel tip

Hi - I am travelling to the Aeolian Islands mid August (Ferragosto). Panarea is a stop on the trip, over the weekend.

Is the hotel raya worth it/ nice at all? Older reviews all indicate it was once the top place to stay in the island, however, more recent on trip advisor say otherwise (dated, not very clean etc.)…

I don’t want to miss out if it is the best place/ great atmosphere but will be very disappointed with an unclean room for the price.

Also is 3 days too many on panarea?

Any other tips/ places/ restaurants to visit would be appreciated.

Thank you in advance!!
