We stayed a month and Konstantinos place is good, it has all you would need, and it's good value. It's also central. If I knew what I know now about that neighbourhood I probably would have booked elsewhere though it's a tough neighbourhood, not dangerous, in our opinion just unpleasant. Konstantinos place is about 100 M from the Metro station, and it has a lift, so that's super convenient. Konstantinous and his buddy Nikos are super friendly and took care of us like family, the good kind of family that is!
