If you want to live in traditional Greek apartment this is for you.
You really feel like you are not a traveler but a citizen of Thessaloniki. The area around the building is very typical for old town with narrow streets and old buildings. For your notice, the area is in the middle of the hill, quite steep climb, so you if you are not sporty in my opinion it can be a little bit difficult for you. We were with kids so we regularly used taxis, as to go down is easy and to go up is not so easy.
The apartment has all you need. On the table there are printed tips from Pantelis that are very useful in terms of shops, cafes etc.
1 big hall with big table and 3 rooms make the living very comfortable. AC is only in the hall, rooms have only ceiling fans that just chase air. Kitchen has all necessary so we felt like home. What is also pleasant after arriving we found coffee, tea, sugar etc as we were not obliged to run to the nearest café for that and could rest a bit.
