Ionna's apartment is perfectly located and just near to many restaurants and bars and also near to the seaside. Me and my friend were only searching for a place to stay for one night since we were coming from Skiathos the day before and flying the next day from Thessaloniki. Ionna's place was just perfect for that, very standard, perfectly located, in walking distance from the place where the ferry arrived and next to a bus station for the airport.
The bathroom was though small and if you're taller than ca 173 cm you would not be able to stand upright in the shower, it didn't bother us since we're both 167 cm :)
We also had difficulties by opening the door like some other reviewers which was a bit tough but all in all a very good apartment for it's value.
What was very outstanding was the communication with Ionna since she gave many very helpful and detailed tips, was super friendly and quick in responding and it was also a very nice pleasure to be greated with a small note on the table with details about the apartment. Would recommend!
