Irini's place is at a fantastic location in Oia. It is literally right beside the main bus station. One of the big advantages of staying here is that we didn't have to drag or hire a porter to carry our luggage up and down the tiny stairs. It also meant that catching the bus to Fira is super easy and we were able to leave the house just before the bus was going to leave. It is also very close to the church of Panagia, just a short 5min walk.
Irini is currently not on the island, but we were met by her lovely artist friend Athina. She was waiting for us right on time by the bus station. We arrived very early in the morning (6:30am) and she was able to let us into the apartment and settle down promptly. she took very good care of us such as ordering a taxi back to the airport for us, as well as reminding us about the day light savings time change.

Irini's apartment is very clean and has plenty of hot water and heating for the colder winter months.

Please note that this place currently does not have wifi, but Athina was able to help me purchase a sim card which lasted us the whole week while in Greece. There are also wifi from various nearby restaurants. One place that we were able to connect to was the "Blue Sky Cafe".

We had some problems using the door keys. It's a very finicky door:( However Athina dropped by after her work and oiled the door for us which made it better.
Irini replies my messages very promptly and very helpful ! Overall, a very nice choice for Oia. :)
