Zannat is a very friendly guy and speaks perfectly english. The room is simple but clean. Outside it can be noisy nearly all night, but the closed window quietens very good.
The region has inspite of what other comments say as well good sides: a park is nearby, where you can rest or recover from sightseeing. The Euripides street next to Zannats street has a lot of shops with herbs an spices, there's an orientalic smell in the air. Not to forget the night life in Psiri: uncountable bars, cafés, taverns.
For everybody who just need a bed to sleep and doesn't want to spent his time there, I highly recommend Zannats room.
