The sleepbox is exactly as described - yup, it's small but it's awesome. The room is a testament to how thoughtful organization can go a long way! I loved that out of the bedroom window, there is a beautiful view (although I can't remember the building in the view - but it's beautifully lit up at night). And the location comes with a wonderful terrace where you can have a little peace and quiet away from the crowds and still have a view of the Acropolis. On my night there, I grabbed a beer from a little store nearby, relaxed on the terrace and listened to the nightlife below me while I enjoyed the breeze and the view.
And Theo is incredibly nice and hospitable. He gave me a great list of suggestions, helped me figure out what to do with my luggage while I toured around the next afternoon before I caught my evening flight.
This place and Theo are a gem. Yes, the SleepBox is a little quirky but that made it all that much cooler of an experience and a story for my friends. :-)
