I stayed in Ioanna's place for two nights as I visited Thessaloniki for a meeting in the university. I didn't meet Ioanna because my arrival and departure times did not fit her schedule. But she was very reactive and friendly, and arranged everything very well. Her apartment was in a great location for me, walking distance to both the university and the seaside. I didn't spend a lot of time in the apartment. Slept well, no troubles with noise during the night. Overall, I had a positive experience. Thanks Ioanna! :)
