We highly recommend staying at Dimitri's and Pakis place. We are a family with 8 and 5 year old children. It was a extremely clean, modern and comfortable apartment. With separate room for us and one for the kids. The beds were very comfortable and the rooms spacious. I loved the fact it had a washing machine, drying rack and ironing board which is a must when travelling with kids. Dimitri and Paki were a delight to communicate with. Always very prompt and helpful with their replies. We had hired a car (parking in town is difficult) which in hindsight wasn't needed if you plan to only travel around the city center as the buses are right in front, a taxi is only 3 euro to Aristotle square or otherwise just a 10-15 minute pleasant walk. We felt right at home at the apartment and would definitely recommend it to anyone who would like to stay at Thessaloniki.
