Ioanna's place is a nice super-clean, wonderfully located, and ultra value for money place in the center of Thessaloniki.
My suggestion is that the bathroom / toilet area arrangement should be very clearly communicated in the listing through a few pictures and a detailed description as to avoid misunderstandings and surprises from all sides. Other than that Ioanna is a caring host ready to help and accommodate feedback. Her parents who checked me in are extremely polite and warm people and want to mention once again that the place was very clean.
