My friend and I stayed at Rhapsody apartments and totally enjoyed it! It's definitely once of the best value places in Santorini.

Location for price is great, but be comfortable with hills! (If you're coming to Santorini, expect this everywhere) You are a 10-15 min walk (steep downhill on the way there, uphill the way back) to Firostefani, and a little farther to Fira. Most places in these locations are way, way more expensive so Rhapsody is a great deal for a little bit of waling in comparison. Plus, the views near the apartments are amazing. It's also right near Skaro rock.

George was very helpful. He coordinated our transportation from the ferry on arrival, to the airport when we left, and gave us some info about the hike from Fira to Oia.
