We stayed at Koutalas Resort during our summer holidays with our dog and we had an amazing time! The beach was very close, so we could walk there every day and despite the fact that it was windy, it was the only one which was calm and nice on the whole island. We had some issues going from the port to the apartment and our hosts were very kind to come and pick us up! They had also bought some treats for our dog which was a lovely thought. We totally recommend this place to anyone who seeks for calm holidays and if we go back to Serifos next year we will try and book this place for sure!
