Callia collection is located near the main square but a bit of a walk because of winding alleys uphill. We visited in March so were not able to enjoy to outdoor pool but the view was still beautiful. The breakfast was very nice and was slightly different for the 2 mornings we were there. The only issue is that the hot water would run out at night so we took some chilly showers.
Checkin process was easy and smooth. The front desk has a lot of information for local tours and things to see and do. We rented a car for the first day and there is a spacious park a short 2 min walk away.
