Great little place to crash. Nice and clean. Very walkable from the Syntagma train station.
I arrived VERY late... maybe 1:30AM? The only challenge I had was that the *first floor* elevator door was locked for some reason I took the stairs instead. My luggage was comically large so it wasn't ideal... BUT all in all, no biggie! I hope someone got to review the security cam footage of me cursing and swearing as I packed a gigantic box up 5 flights of stairs.
I'd recommend staying here!
