Me and my girlfriend had an amazing stay here! Communication with the Stefos was on point and he provided us with important information about city commute which was really helpful.
Apartment is located ~100 meters from bus station which is convenient because there is a bus line taking you directly to the city centre (and back), so you don't need to worry about that.
Apartment itself is amazing for two. It is clean, has everything you need (and more) and we really enjoyed our time here. Since I work remotely, few days during our visit I had meetings from the apartment and WiFi was fast and stable which is great for digital nomads who want to stay longer in Thessaloniki and work from the apartment.
I cannot recommend this place enough! If I were to visit Thessaloniki again (which I am planning to) I would definitely stay at Stefos again!
