Thalassa Boutique Hotel

Adults only in Lassi, with a rescue dog as the house mascot

This hotel is part of the Daisy Curated Collection. Its information has been researched and verified, but Daisy has not yet personally stayed here. When she does, this page will be upgraded to a full Daisy Verified inspection.

Daisy's Assessment
Researched and verified. Not yet personally stayed.
A 55-room adults-only boutique hotel in the Lassi resort strip just outside Argostoli, with two pools, a pool bar, a restaurant and a planted garden. It's the only hotel on either island that writes about dogs as if it likes them, built around Simba, the owners' rescue puppy, and it points guests at the garden as the dog's space. Makris Gialos sand is about ten minutes' walk downhill. Adults-only, so it suits couples travelling with one well-behaved dog rather than families.

Why it's in the collection

Paliostafida, the small cove just along from Lassi, sits outside the Blue Flag scheme, and the Koutavos lagoon boardwalk in Argostoli is a flat, shaded twenty-five minute circuit with loggerheads in the harbour at the far end.

Best suited for

The garden is the dog's part of the hotel, and the rest is worth confirming when you book.

The open question

How the welcome translates in person, at dinner and around the hotel. That's what a Daisy stay will confirm.

The garden is the space the hotel names for dogs. Makris Gialos, the sand at the bottom of the hill, carries a Blue Flag, and Greek law closes Blue Flag beaches to dogs all year.

Where we can't yet confirm a detail first-hand, we mark it plainly rather than guess. A Daisy stay will close every gap.
