Spacious and clean private space with excellent air conditioning. A nice outdoor area, with a beautiful resident white cat (please consider giving her some treats, she's so lovely!) Quiet and peaceful setting behind a bigger hotel. A very nice shower with waterfall and detachable heads. The only issue was the WiFi not reaching the property, but this probably helped me enjoy the local area more. It's a short 10 minute walk into the centre, where there are plenty of supermarkets, restaurants, coffee bars, pharmacies, etc.
If you're flying in and not planning to explore much, get a taxi to Argostoli and catch the ferry rather than hiring a car. It's quicker and much cheaper.
