The place is great, Georgi was waiting for us as we arrived. It was 20 euros on taxi from the Airport to the apartment and then if we wanted to go to the center or the bus station on taxi it would be around the 6-10 euro mark.
The place was really clean, the kitchen big and with everything you might need to cook including oil salt and pepper, more than enough plates and glases for 4 people or even more. It also had a big fridge with freezer that was clean and perfectly functional. The place has confortable space for 6 people to sleep.
The bathroom has what it seems to be the standard in Thessaloniki that i could find which was no division between the shower and the rest of the floor. This means the floor gets wet whenever you take a shower, but it gets dry on its own by next morning if you shower at night.
The apartment is on the first floor and has bakeries, a supermarket and a convenience store all quite close. The promenade is only 2 blocks away and you can reach the city center by walking around 15min.
Overall i can highly recommend this place and Georgi as a host who always answers your messages if you have questions.
