I loved my stay in the sleepingbox! It's the perfect place for a solo traveler. I met Theo only on the last day when I came back to the apartment to pick up my luggage, but he was always available for questions and provided me all the information I needed (about the self check-in for example). The room is clean, stylish and comfortable and on a walking distance from the metro (great connection with both the port and the airport), restaurants and all the main attractions of Athens. Thank you Theo and team!
