Xrusa's place is amazing. It was only a 5 mins walk to Fira's center & Fira's bus stop. It is also only a 20mins drive to the airport. We hiked from Fira to Oia and it took us about 3 hours, mainly bcos we were constantly slowing down to take in all the sights). Fira is where all the buses are so staying here was definitely the best decision we've made this trip. Santorini, without needing to say anything, is breathtaking.
