The rooms and suites are individual in their layout and position. A terrace is part of even the Deluxe Room, so outdoor space is not confined to the larger suites. The standard Deluxe has 32 square meters indoors and a 13-square-meter terrace, furnished with seating and facing the caldera. Inside are a king bed, a white sofa, and a natural wood reading desk. The bathroom has an oversized shower.

A Deluxe Room with Plunge Pool adds a heated outdoor pool to its terrace. This distinction also appears among the Junior Suites, which are available with or without a plunge pool. The category name matters here: a private terrace does not automatically mean a private pool. Across the accommodation, the outdoor arrangement is as important as the bedroom, particularly for guests planning to spend an afternoon at the hotel.

Junior Suites have extended terraces with outdoor seating, while the Superior Suite with Plunge Pool combines a terrace with a heated outdoor pool. The Grace Suite goes further, with a hammam steam bath and an indoor plunge pool as well as an outdoor plunge pool. It has 63 square meters of interior space and a 33-square-meter terrace with sun loungers. A rain shower completes the indoor bathing area.

The Infinity Suites sit adjacent to the main hotel, with access to its services and facilities. Each has a king bedroom and a separate living room within 50 square meters of interior space. Outside, a 55-square-meter terrace holds a heated private infinity pool, lounging space, and an area for dining. A marble bathroom with a steam room and a separate dressing area complete the layout. The division between bedroom, living room, and terrace gives these suites room for a longer stay without relying entirely on outdoor space.

The Villa has a three-bedroom configuration and 400 square meters of combined space: 150 indoors and 250 outside. A full kitchen and dining area make private meals possible, with a chef available by arrangement and a dedicated Villa manager overseeing the stay. Its heated swimming pool sits beside an expansive split-level terrace with a gazebo and an outdoor fireplace. The living and dining areas give a group somewhere to gather away from the bedrooms, while the terrace looks across the caldera.

For families, The Villa is also the exception to the hotel's usual minimum guest age of 14. Younger children can stay here, and cribs are available for this accommodation only. The concierge can help arrange childcare, and highchairs can be requested. Children's menus are available in the restaurants and through in-room dining, so meals can be planned either in the residence or elsewhere in the hotel.

The hotel's 22-meter infinity pool is its main shared outdoor space. The long waterline faces the caldera, with loungers nearby and a poolside bar providing food and drinks. Unlike the smaller plunge pools attached to individual rooms, this pool has room for a proper swim. Its position draws the surrounding cliffs into the view from the water, and the terrace remains a place to spend time even without swimming. Breakfast, a swim, and a rest outside can fill an unhurried morning here.

Varoulko Santorini brings chef Lefteris Lazarou's approach to Greek and Mediterranean cooking to the hotel. Seafood and local seasonal ingredients anchor the menu, accompanied by a selection of Greek wines. The setting includes a show kitchen and outdoor tables in alcoves or beside the infinity pool. The restaurant serves breakfast, lunch, and dinner, with a smart-casual dress code. At breakfast, a changing set menu gives the morning meal its own character, separate from the seafood-led cooking later in the day.

At 363 Bar, cocktails curated by Athens' Baba Au Rum introduce another Greek connection. Local spirits feature alongside international ingredients, while the view takes in the volcano and Skaros Rock. Champagne is also part of the selection. The bar's name refers to its elevation above sea level, and its terrace is a natural setting for a drink as the light changes over the caldera.

Wellness at Grace is personal in scale. Treatments take place in the guest's room, not in a communal spa complex. The menu includes a traditional Greek olive-oil massage, and the hotel uses APIVITA products. The hammam and steam-room features in selected suites remain private accommodation amenities.

There is also a fitness center and a yoga and Pilates studio, with personal training available. Guests can arrange sessions ranging from stretching and circuit training to yoga. An in-room fitness kit provides another way to exercise without leaving the accommodation. The facilities keep movement part of the stay while retaining the hotel's small scale.

Wine tasting at Grace introduces selected local wines with food to accompany them. For a wider look at Santorini's wine culture, the hotel arranges guided winery visits that can include lunch at a local farm. The two experiences have different settings: one stays within the hotel, while the other brings vineyards, cellars, and an island kitchen into the day.

Private yacht and catamaran outings explore the island from below the cliffs. Routes can take in the volcanic coastline and Thirassia, with daytime and sunset options. These are separate excursions, not beach facilities at the hotel. A boat trip gives the caldera a different scale from the high terraces of Imerovigli, with the villages seen along the rim above the water.

Grace Hotel is reached by descending several flights of concrete steps, and the cliffside layout can be unsuitable for guests with restricted mobility. The concierge arranges private transfers from Santorini Airport and Athinios Port. The hotel's estimates are about 20 minutes from the airport and 30 minutes from the port, depending on traffic. Arrival arrangements need to account for the final stepped approach as well as the road journey.
