Skevos picked up up from the ferry and gave us a quick tour of Pothia (he also dropped us off at the ferry when we left). The flat was as advertised and stocked with some staples (cereal, milk, juice, butter, bread, and a bottle of (very tasty) wine) to get us started. Katina and Skevos were incredibly accommodating and went out of their way to ensure we had a good stay. It should be noted that the water isn't potable (it was fine to cook with), and they suggested sticking to bottled water, which was quite inexpensive. The flat is very close to both Masouri and Myrtees, with multiple stores, restaurants, and beaches a short walk away. The location is excellent for accessing climbs (and renting scooters), and many crags are within a 10-15 minute scooter ride from the flat.
Overall, we had a wonderful time and absolutely recommend staying with Katina and Skevos. The flat was lovely, the location beautiful, and the hosts were fantastic.
