We loved staying at Ersi Villas. Elias was super helpful and on the first day went over our trip with us, recommending places and giving us information about the local area. The room itself was super clean, comfortable, and everything worked great. The location is very close to Fira, but far enough that you are not swamped by tourists every time you leave the front door. :-) The main shopping lane of Firostefani is only a few minutes away, and it's a really nice place to relax and eat. I would totally stay here again and recommend it to anyone who wants to stay in Santorini. Thanks Elias! :-)
