We found the studios to be as described and were good value by Santorini standards. We arrived at midnight and Roussetos organised a transfer from the ferry port with his driver. He was there waiting for us and drive very safely and carefully. He showed us to our room. We didn't expect anything fantastic and the room is basic but spacious and generally clean. Amenities are a little tired and we found the bedding and towels to be a bit old and grey but that is likely in part due to poor quality waters which we found very salty and couldn't even use it for teeth cleaning.
The bathroom door handle was missing completely so we could not shut the door but this will likely be repaired now they know and there were some light bulbs missing but pretty minor really.
We were unfortunately not able to use the room on the last night we paid for as our ferry left at 03:20 and we had to depart for the port at 23:50 which meant no sleep. Had we known we would have checked out that morning as we were out all day anyway.
We hired a scooter from the hire shop next door to explore the island. For sure Perissa is much quieter than the rest of the island which we found great. The location was quiet enough and it was pleasant to sit on the small balcony in the early evening. All in all a good experience and would stay again
