The Sleepbox offered by UnspoiledAthens is a unique experience for a cost conscious, single traveler accustomed to urban living in a tiny space. It's your own, private, full featured room, with some nice amenities. The free laundry facilities are steps away, with washer, dryer, hanging racks, and all the supplies you will need. Unfortunately I didn't have time to use the complimentary bicycle.
The separate toilet/shower, on a lower floor, makes for an expectedly bracing nighttime interlude to use the facilities.
The UnspoiledAthens team was great to work with when another host cancelled my existing reservation a week before I arrived!
