Embrace the art of slow living at this 5-star family-owned luxury resort on Kos’ glorious coast – reserved exclusively for adults.

With sustainability at the core of its ethos, the Theros All Suite Hotel’s roots lie with the Mastrominas family, descendants of which still run the property today. An adults-only hotel, it’s hard not to fall in love with its Greek-inspired architecture, stunning accommodation, authentic farm-to-table gastronomy, indulgent spa and bespoke experiences.

About Theros All Suite Hotel

Inspired by Kos’ classic Mediterranean landscapes and by the island’s traditional architecture, the Theros All Suite Hotel is a 5-star coastal sanctuary reserved exclusively for adults. Tucked just behind a beach on the island’s northeastern corner, the hotel embodies the charm of a Mediterranean garden, boasting olive trees transplanted from the Mastrominas family’s personal groves plus endemic flora, palm trees and aromatic herbs dotting its grounds. Beautifully designed with earthy tones, each secluded suite at the hotel lies centred around an inner yard and is environed by Mediterranean gardens to produce an atmosphere that is both authentic and blissfully tranquil. The hotel’s sustainability-driven philosophy is evident in its sumptuous farm-to-table cuisine, whereby locally sourced and homegrown ingredients are incorporated into a delectable variety of regional dishes and Greek classics. So too does the Ef-Zin Spa draw on the island’s nature, applying fragrant, medicinal herbs from the garden to its soothing treatments. You can also work on your wellbeing at the modern gym or take part in a mindful outdoor yoga session. While the beach is just moments away and the hotel pool is beyond temptation, the Theros All Suite Hotel’s concierge staff are also on hand to help curate an experience or activity tailored to your needs. From herb-picking in the resort gardens to discovering the island of Kos by cycling, hiking or sailing, to going local with immersive cultural activities like cooking classes, wine tasting, visiting local farms or cruising the crystalline waters to nearby islands – you’ll be able to discover the essence of this evocative Greek island.

  • Latest Updates

    New Schengen entry requirements (planned for November 2024 onwards)

    From November 2024, the new EU Entry/Exit System (EES) will start for all non-EU nationals, including British nationals, travelling in or out of the Schengen area. The Schengen area is made up of 29 European countries, 25 of which are EU Member States. The EES is a digital border system which registers non-EU visitors travelling into the Schengen area instead of stamping their passports.

    You will need to have your fingerprints and your photo taken when entering the Schengen area. If you enter the Schengen area through Dover, Eurotunnel at Folkestone or St Pancras International, your fingerprints and photo will be taken before you leave the UK. You will also need to provide either your fingerprint or photo on exit.

    You may experience longer queues at borders when the new system starts.

    Passport, Visas and Local Taxes

    Your specific passport and visa requirements, and other immigration requirements are your responsibility, and you should confirm these with the relevant Embassies and/or Consulates. We cannot accept responsibility if you cannot travel because you have not complied with any passport, visa or immigration requirements. 

    The Greek Government has introduced the Climate Resilience Tax, payable locally upon check-out by the customer.  This tax does not form part of your holiday package as we are not able to collect this at time of booking.
