Great location in the Plaka district. Super close to Acropolis, Syntagma and Monastiraki. Staff was super helpful. I was upgraded to a better room my first night and ended up staying three more nights. They have a travel agent right inside the hostel who is very helpful booking tours and ferries too. Nice courtyard lounge as well.
Nina and Daniel are great! They give great advice about Batumi and other places to go in Georgia, it helps that both speak excellent English. Great vibe, atmosphere, and location make this an ideal hostel environment :) leave them a message when you make your booking and they're happy to accommodate
Rooms are a bit hot, a floor fan would be immensely helpful.
