Es Vedrà appears across the water from the pool terrace, while the beach is close enough that sand can become part of your evening footwear.

Adults only, sea views, a poolside bar and Mediterranean food: UNIO Ibiza - Adults Only is set up for couples and adult friends who want the diving day to end without another round of family logistics. The atmosphere is deliberately grown-up, with bright, simple décor and gardens around the pool rather than a long list of distractions competing for your attention.
English is spoken by the hotel team, alongside Spanish, so you can deal with the practicalities without resorting to underwater hand signals at reception. The hotel website also serves English, Spanish and German-speaking guests. That matters when you are arranging arrival, discussing dinner or trying to explain that the room key has chosen a life of its own.
This is a place for an adult break with the sea close by, not a family resort. Children are not accommodated, and the hotel keeps the setting centred on the pool, terrace, restaurant and the coastline around Cala Vadella.
The hotel is in Cala Vadella, on the south-west side of Ibiza, with the sea 50 metres away and a golden-sand beach reached on foot. Cala Carbo Beach is about 0.7 miles away by car, while Cala d'Hort Beach is around 1.1 miles away on foot or 2.6 miles by car. Cala Vadella Beach itself is about 1.4 miles away on foot, or 2.1 miles by car.
The immediate setting is coastal, but you are not cut off from the island. Sant Josep is around a ten-minute drive away, and Ibiza town is around five minutes away according to the hotel information. Nearby dining includes La Mesa Escondida - Cocina Mediterránea, about 300 metres away, while Restaurant El Carmen is around 2.3 miles away on foot.
For a change from the coves, Torre del Pirata is about 2.9 miles away by car, and Sa Talaiassa is around 4.3 miles away on foot or 7 miles by car. Ibiza Airport is about 12 miles away, with a driving time of roughly 25 minutes.

The room choice is mainly about how much space you want around the dive bags and whether the view matters. The Studio with Sea View and the Duplex Suite suit two adults who want a compact base, while the apartments give you separate seating areas, kitchenettes and outdoor terraces. The larger apartments are the sensible choice for adult friends travelling together or for anyone who dislikes having to stack every possession vertically after a day on a boat.
Sea-view accommodation puts the coast into the room rather than leaving it for the walk to the pool. The apartments add a terrace, a kitchenette, a refrigerator and an electric kettle, which gives you somewhere to keep cold water and a place to make a drink before dinner. The Standard Double Room is the compact option for two, with a large king-size bed and a private entrance.
Air conditioning is available throughout the accommodation, a useful detail when salt, heat and a full day outdoors have done their work. Bathrooms are private and include a shower or bath, towels, toiletries and a hairdryer. Daily housekeeping keeps the room in order, while a wardrobe, clothes rack, laptop safe and safety deposit box cover the less glamorous but entirely practical side of travelling with watches, wallets and small electronics.
Breakfast is included and served as a buffet, with continental choices in the morning. The listed breakfast service runs from 07:30 to 10:30, giving you a reasonable window before a boat departure or a slower start on a non-diving day. The restaurant also serves dinner, so you can return to the hotel rather than making every evening a search for somewhere open and nearby.
UNIO Restaurant works with Mediterranean cooking and sits on a terrace overlooking the sea. The dress code is smart casual, which means your post-dive clothing can remain practical but should probably stop short of looking as though it has just been recovered from a rinse tank. The terrace also looks towards Es Vedrà and the hotel gardens.
UNIO Bar is the only bar listed and is positioned beside the pool. It specialises in cocktails and refreshing drinks, while the restaurant and bar serve drinks through the day until sunset. Limited-hours room service is available, and special-diet menus can be arranged on request. The overall formula is breakfast included, with dinner and drinks available at the hotel rather than an all-inclusive package.

The main outdoor option is an adults-only pool with sun loungers, umbrellas, pool towels and a bar in the water. It is the obvious place to spend the afternoon when the body has had enough of fins but the day is not ready to end. The pool is outdoors and unheated, with the terrace and gardens providing the setting around it.
The nearby beach brings a different kind of post-dive pause: golden sand, loungers and parasols, all within 50 metres of the hotel. Snorkelling, kayaking and paddleboarding are available, with equipment hire and boat excursions adding a little more scope when you want to remain on the water without committing to another dive. Hiking and cycling suit the cooler part of the day, and excursions include a visit to Ibiza town and a boat trip to Formentera.
For a quieter recovery session, the hotel has a fully equipped gym, along with massage and beauty services. That gives you a choice between moving deliberately and not moving at all, both legitimate responses to a full day in the sea. The gardens, sun terrace and outdoor furniture provide the useful middle ground: somewhere to sit with a drink, dry off and decide whether dinner is worth changing for.
The hotel is adults only, with a minimum age of 18. Check-in runs from 15:00 to 23:00 and check-out from 07:00 to 11:00. You need photo identification and a payment card at arrival, and the hotel needs your expected arrival time in advance. Early arrival and late departure can be requested.
Ibiza Airport is around 12 miles away, roughly 25 minutes by car. An airport transfer can be arranged on request, and car hire is available through the hotel. On-site parking and street parking are available, while luggage storage is useful if your flight times do not line up neatly with the room. The hotel also offers a concierge, laundry and dry-cleaning services.
Free WiFi is available, alongside air conditioning, non-smoking rooms, a private entrance and key access. Payment is accepted in cash, Visa and Mastercard. Pets are not allowed, and cots and extra beds are not available; extra beds apply only to apartments. The hotel has a safe at reception as well as a laptop safe in the accommodation.
