The is a very lovely appartment with a bohemian spirit. There is enough place for at least 6 people. We had no need to use our car or any public transport while in Thessaloniki: The appartment is located in the old city and it only takes a 20 minutes walk to reach the sea ( white tower)
Pantelis mother has been very helpful during our check-in/out and whenever we needed sometime.
All of this made our stay in Thessaloníki very productive and enjoyable.
