I have stayed in many flats in Thessaloniki, and must say this was one of my best stays! The pros: superb location right next to Aristotelous Square, spotlessly clean, big bed with good quality pillows, a kitchen with fridge in case you want to prepare something, spacious, and a cool balcony. As quiet as you can find in Thessaloniki (not easy!). Very much enjoyed my stay, and will be on the top of my list for my (many) upcoming trips. Excellent value for money. The only very small negatives: water pressure is low (probably building-related) and the matress is a little bit hard. Last but not least: excellent communication and very easy check-in.
