Very short walk to the main part of Oia where all the shops and restaurants are located aswell as the bus to the airport. Avoid taking a cab if you can -40-70 euros one way - bus is supper easy and cost 3.10 euros each way.
Pool area is awesome - lots of space and very inviting to spend an afternoon with wifi access.
The host Sotiris will make sure your stay is as planned and is available if needed. I would recommend staying if you don’t want to stay up in the main part Oia which will a lot more $$$.
