Plus: The hotel rooms are extremely tastefully decorated, in a simple mediterannean style. Great location, about 10 mn walk from/to Panarea center & port, and another 10 mn to the nice Zimmary (sandy) beach. On the way to the beach are a trattoria (great salads!), and a bar (coffee, snacks). Behind the beach the path winds up a hill towards the ruins of a historic settlement.
I was picked up from the port (call upfront and provide your arrival time!), and helped with carrying my luggage up the steep stairs to my room. On the beautiful terrace above it (belonging to another room though, which happened to be empty), wifi connectivity was reasonably ok.
Minus: My room was not that quiet retreat i had hoped for: There were squeeking water pipes, loud voices (mostly the owner!), traffic running up and down the street between the buildings. Also, the moscito screens weren't tight and the room not sprayed, so that i had to deal with mosquitos in the nights, and bites in the mornings. The shower hanger was broken, and no visible effort for replacement. Its true the breakfast included some sweat bakery stuff, but basically toasted bread slices, jam (great self-made orange an lemon jam!!), yoghurt, juice and fruits, and I had to ask/confirm everything, every morning. Wifi in the breakfast area was weak, and I was not offered access to any other public area. Finally, i did not receive free transport to the port upon my departure, since i needed it later than 11am (check-out time). hm.
