Great flat, very clean, large and comfortable. Sandy was super reliable and gave fantastic tips (particularly the ones for breakfast were amazing). The location is ideal for strolls in Ano Poli and to quickly get to any area (whether on foot or by bus/car) of the bustling inner city.
Sometimes it was a bit chilly in the flat as there was no heating (the airconditioning helped a little) - but this is rather normal for Thessaloniki in winter and could have happened anywhere else.
I definitely recommend this Airbnb.
