The property had plenty of room, and a patio looking up at the cliff where ancient Thira is located. The hotel staff was very nice & helpful.
Perissa is quieter than other beach towns on the island, which may or may not be a good thing. The bus stop to Fira is an easy walk, a few hundred meters away. The beach is another 100 meters from there.
The biggest downside was that there wasn't wifi in the rooms, only in the common area.
