This apartment was perfect for our time on Santorini. It is about a two-minute walk from the main square in Fira, which is the capital and largest town on the island. The buses, which you can take to the beach, to Oia, etc. also stop near here. (I would recommend staying in Fira over Oia because it is much more centrally-located).
Anyway, this space was great. It was larger than it appeared to be online, with both a spacious bedroom and kitchen/living area, and there was a large deck that we had private use of. The apartment was nice and quiet, too.
Andreas and Vivi were very kind, and they gave us some tasty dessert wine and treats that Vivi had baked. They were also willing to store our bags prior to our late evening flight out of Santorini. Andreas even stayed and chatted with us for a while when we were waiting for our airport transfer, which he arranged. Recommend this spot!
