Located at Firostefani, Ersi Villa is a great place to stay in if you are seeking for some quiet and peace, but yet is also convenient and close to Fira town center. Also a good starting point for walking to Oia.
There are some steps and slopes up to the main road, but is doable with small luggage. Recommend taking the Taxi/transfer from Port to the Villa as it's an uphill walk from Fira Bus Station. We walked the way back with our luggage and it was an easy downhill wall.
Ersi Villa offers the other view opposite to the Caldara, but the Caldara view is just 3-5mins walk away and the sunsets are beautiful there.
