Kostas place is great! Stylish and cozy, warm and homey with an amazing view of the old archeological museum to wake up to. Location a 15+ minute walk from the center center (busses are close by) and close to the water/nice promenade. Nice food outdoor market just around the corner. Very local ("real") vibe all around. We were two couples staying there, and for sleeping, there is a double bed in one room and two singles (the second single is a pull out bed placed underneath the other) in another room. Amazing sofa chill out space. Love the vinyl collection. Fast internet. Easy, friendly and fast communication. Highly recommend Kostas' place for a stay in Thessaloniki!
