I absolutely recommend Dimitris place. It's huge, minimally furnished and has great character. You're quite high up and consequently it's nice to look outside from the half dozen large windows. Close to bakery, market and walk to metro. We walked to the acropolis in less than 15 min. Fast wifi. As for Dimitris himself he was perhaps our favourite host of around 15 others. We would be most happy to host him. The value of this place is unbeatable
