I was in the Hermitage Hotel and Park Terme in July 2007.
The places are very nice, but not the hotel Hermitage!
I booked the hotel for a long relaxing week-end but we had some problems.
The room: the air conditioning didn't work very well, mini-bar wasn't stocked. Old room not with 4 * furniture. Our balcony was big and with a nice view.
The two thermal pools weren't thermal, but normal pool and not so clean.
The room smell smoking. When we booked, we asked for a non-smoking room, but this hotel doen't have smoking and not smoking room!
The morning breakfast is absolutely poor! not an english or american breakfast!
What I liked? the view of the castle and of the surronding area.
The hotel is overprice!
Sorry if my english is not perfect!

Well after reading a review of Hermitage Park Terme from a reviewer who was not of a good opinion of the Hotel, the four of us who had booked to stay for a week were a bit dubious to say the least. We booked from the 17 Sept - 24 Sept. After staying there for a week it became clear that this opinion was nonsense!
These are my/our replies to the review:
The Air conditioning was perfect and much needed. There were two radios one on the wall and the other was part of the TV both worked ok. I agree that the mini bar was not stocked but that was good because we bought our own drinks and kept them cool in the fridge. The TV was of ample size with a wide variation of channels the only English one was CNN news. Our balcony’s were excellent we were on a lower annex down from the main Hotel we had clear views of the castle and surrounding areas. The pools and yes there are three pools one is on the lower floor in the fitness area of the other two one is the main pool which is heated but I agree not too warm and the other is the mineral pool which is not green but a browny colour and was very warm and was great. There were two other water areas, one was a waterfall that released warm spa water onto you as you sat on tiled seats and the other was an elliptical walk through that was on pebbles and was apparently to aid circulation. The shuttle bus to the beach was free and ran at 9.30 and 10.30 in the morning and picked you back up from the hotel beach at 1.00pm and 5.00 pm. The food in the restaurant was excellent and had a wide variety, we were half board so i cannot comment on the price. We all agree that the prices in the bar area were very high and we took to going next door to an excellent bar for a drink which was very well priced and had great value for money. The very friendly reception area spoke English. The waiters spoke enough English to get by (we do not speak any Italian). There are a couple of supermarkets quite close by and an nice walk to the beach area about 10-15 minutes down hill and about 15-20 minutes up hill. I agree there is not a lot to do for kids but as we were four adults this did not bother us nor did it seem to bother people with kids that were at the hotel. I/we would certainly return both to the Island and the Hotel and would recommend people to visit and stay there.

My husband and I thought we would get away for a romantic weekend (we live in the Naples area) and take the inexpensive ferry over to Ischia island. The island itself is fabulous. The Hotel Hermitage was not. We booked the priciest room there thinking it to be the best. A/C did not work, radio was broken, mini-bar was not stocked, tiny TV, view from balcony partially blocked by hills, the two "thermal" pools were not thermal in anyway. One is a regular pool and the other cool cloudy green mineral water. Pool closes at 7:30pm (WAY too early) and their advertised shuttle to the beach is actually you hiring a microtaxi for an overpriced 10 Euro each way. The tennis court was filled with leaves and other floral debris and we saw no indoor pool as the site advertised. The restaurant was OK (friendly staff) but WAY overpriced and almost no one spoke English (which they advertise as well) and the ones that did new only basics. Thank goodness we can speak some Italian. Anyway, We would NOT recommend this hotel to anyone, especially with kids as their is nothing to do after 7:30 pm when the pools close and its a bit of a hike to the nearest good shopping areas.
