Dreamlike day in the Poseidon gardens and thermal baths - I can recommend the Poseidon Gardens to anyone who comes to Ischia. It was a great day that was very well organized. The pick up and transfer from the hotel to the spas and back was on time and the driver was very friendly. The 22 thermal pools right by the sea were a dream. The gardens are clean, there are plenty of changing rooms, showers, lockers and loungers and the food in the restaurant was very delicious. Always happy to come back 😃

Wonderful - We return for the third time after a few years of absence, unquestionably beautiful and regenerating, attentive and courteous staff. If there were facilities for families we would gladly return in the following days.

A relaxing day - Every year we return to the Poseidon gardens xchè a day worth them a stay in the 'island of Ischia. Fantastic thermal pools. Friendly and helpful staff. Lunch at the self service is great. Everything is taken care of in detail. Highly recommended

Beautiful but improvable - Ischia in May would be a paradise. Then one encounters a stormy weekend and fears that everything will turn out poorly... instead, the sun occasionally comes out, and the Poseidon pools, with all their variety of temperatures, become a beautiful place to spend an entire day. To this, one must add the kindness of the staff, the cleanliness (excellent), and the self-service option, with local food at reasonable prices. However, in what would be a panorama of beautiful things, there is a flaw that forced me not to give the highest rating. The flaw is represented by the system of deposits that must be left for any item taken "on loan." And I do not contest at all that there should be an additional payment, compared to the rental fee (there can be), but I find the "how" and a certain vagueness in managing everything absurd. I will try to explain myself. I now go around with a reduced amount of cash; I rarely have more than $50 cash with me, which is more than sufficient in all the situations where I have needed it. At Poseidon, it is not enough because they will ask for cash for the deposit on anything. Not for the rental (a "linear" commercial transaction: I, the customer, "purchase" a service - renting a towel and bathrobe, in our case - and I can also pay with electronic money), but for the deposit. Which, for example, in the case of the bathrobe, is worth twice the rental cost. Therefore, if you "rent" two towels and two bathrobes, you pay $40. But you must leave a deposit of $70. I did not have them, and, of course, there is a solution (there is an ATM immediately outside the entrance), but it should be noted that the entrance is a few hundred meters from the point where towels and bathrobes are rented (so you go back, go to the ATM, withdraw, and return). All of this, if there is a line, takes 20-30 minutes, completely wasted. For an extra charge, there is the "little watch" that you need to access and use some services (like lockers: fantastic not to have to carry coins or bills!), included in the ticket price, which also has a deposit of $5 that must be paid at the ticket office. This deposit can be conveniently paid with electronic money. This explains why I cannot give the highest rating and - I hope... - I would like those in the company who read these comments to draw inspiration to solve the problem (when we complained about this with the staff, we received total solidarity: it seems that this continuous cash flow, which is collected at one point in the facility and returned at another - at the exit, at the ticket office - is also a hassle for them...)
