We had a great week in Fira, Santorini. The apartment is lovely and in a perfect location v close to the main square. The jacuzzi in the courtyard is a real highlight (it doesn't 'bubble' or at least not when we were there but it's really warm & relaxing and perfect for the chilly evenings!). There is also a terrace on the other side of the apartment with table and chairs that's great for breakfast in the sun. The bed is really large and comfortable. We had some issues with the shower temperature - on the first night someone had come out and fix it and for the rest of the week we found that it's often tepid for a long time - however we found that if you run the shower for 10 mins then turn off and back on again after another 10-15 the hot water seems to return).
Argiris was really helpful and gave us a map and recommendations of where eat and what to see on the island and very responsive to any questions we had. Highly recommended.
