Rena's place is excellent. Is a great value for money vs the standard in Oia. Location is great, just a few 5 min steps away from Oia's castle. With stunning views over the caldera, you will enjoy waking to the sea view or just having a glass of wine or prosecco in the evening (both included in the fridge + plenty water + fruits + bread / jams + a lovely cake). I absolutely recommend the place. Also Rena can book you a taxi from the airport or to other places in the island at a very competitive rate (vs Santorini standards), better than Uber.
