The flat of Mery is a good choice for exploring Thessaloniki. You can reach all the touristic places by foot and the close neighboorhood is really sympathic and has everything like supermarkets, really good bakerys and bistros with gyros eg. nearby. We were travelling with our two kids, do we had to carry the buggy upstairs, but we were ok with it. All in all it was a great stay in the charming city of Thessaloniki!
