I stayed here with my daughter (aged 19) as part of our holiday to the Aolian Islands and Taormina. After a very disappointing stay on Lipari, we moved on to the Therasia: they were wonderful and we were finally able to relax: staff were helpful, the manager showed us round himself, the room was lovely, with a big balcony, drinks were great - very nice cocktails, alcoholic and non-alcoholic, food was excellent and breakfasts really good. Others have said they found the dinner menu very limited - it is short, but really good and it does change. We had no problems - and it was well-prepared and presented - looked and tasted good. And, if there was nothing one wanted, they suggested alternatives or amendments to the menu to accomodate that. There is also a bar / snack restaurant by the pool and in high season, 2 restaurants.
When we arrived, our agency had neglected to endure a room with a bath - not just a (very good) shower: as I have arthritis, I need a bath to soak in and this was an essential requirement requested of the agency in advance, made when we booked, but not passed on (not the only error they made). As soon as we told the reception staff, they arranged a room transfer - and we ended with a wonderful room, with sea view, balcony - and bath... And - despite this not being their mistake, they id not charge more for the superior room.
The pool - an infinity pool, was beautiful and the views from hotel and rooms was superb.
We did not use the spa, so cannot comment on this.
Vulcano does not have much nightlife - we did not go out in the evening. We did a day tour with the (at the time) only cab which we really enjoyed. There are quad bikes and cycles to hire for exploring and boats to the other islands daily, water sports etc. We took the long day trip to Stromboli, staying for sunset - well worth doing, watching the volcano there smoke and fire as darkness fell. The Vulcano volcano is also active and was smoking away too rather impressively. There are also sulphur-smelling medicinal hot mud pools on the island - look horrible, but many seem to think them excellent . The hotel has a courtesy minibus to and from the harbour. On one day, we had missed the minibus from the harbour aftrer being out exploring, but one of the hotel drivers was taknig back a party in their larger coach and ran over to us and invited us to join them - I was surprised and impressed he recognised us as we had only been there a day then, but we really appreciated it and not having to wait and it seemed to be typical of the hotel - the staff were helpful and wanted to enhance our stay. The hotel has day trips on a yacht, but the weather was not great during our stay and this was not available - would definitely do this next time.
It is not cheap - but, having stayed at other hotels for more money with far less enjoyment, I think it was worth it.
For a really relaxing break, in a beautiful place, I recommend this hotel whole-heartedly.
We loved the atmosphere of the hotel, the comfort and everything about it. We would both happily return any time.
