We were able to book this place at the last minute (evening of) when our other accommodations fell through. Alexandros was very responsive (<5 mins) and had somebody set up the downstairs bed for us within 20 mins of my first inquiry. Fairly basic place but it was very clean, check in was fully automated and simple, and it had beds for our family of five. Perfect location on a quiet side alley right around the corner (1 block!) from all of the activity in Plaka!
