Atlantica Belvedere Resort - Adults Only
Kos, Kos, Greece · ★ 4.5 Exceptional B.Booking.com 9.0
Private plunge pool in your bathroom, adults-only calm, and a 9.0 guest rating on Kos.
Slip into the water late afternoon, when the Greek light goes amber and the resort goes quiet. At Atlantica Belvedere Resort, the plunge pool sits inside the bathroom itself, so it's genuinely private: no neighbours peering over a fence, no shared terrace anxiety. Just cool water, warm tiles, and nowhere you need to be.
If you're looking for a hotel with a private in-room plunge pool in Kos, this adults-only property earns its 9.0 rating with rooms that feel calm and uncluttered. The photo tells you what to expect: clean lines, sheer curtains, a sliding door that opens straight onto the pool terrace. Sea-view rooms add the Aegean on the horizon; inland rooms trade the water view for a bit more quiet. Both work well.
The honest catch: the pool is compact, built for soaking rather than swimming. Come for the stillness, not the laps.

Questions, answered
Where exactly is the plunge pool, is it outdoors on a terrace or inside the room?+
The plunge pool is located in the bathroom, making it genuinely private. From the photo you can see the terrace sits just beyond the sliding doors, with the pool positioned between the room and the open air.
Is the sea view worth paying extra for over the inland-view rooms?+
The sea-view rooms look out over the Aegean, which is lovely at sunrise and sunset. The inland rooms are a touch quieter and often a little cheaper, so if the view matters to you, it's worth the upgrade, but you won't feel short-changed either way.
How do you verify the tub is in the room in Kos?+
We check with each property that the jacuzzi, hot tub or plunge pool sits inside that exact room or its private terrace, never a shared spa, before the suite shows up here.
Are the tubs private or shared?+
Always private. Every suite on Upgrade Suites has its own in-room or private-terrace water feature for your exclusive use.
