Sokol is a great host. He is very communicative and was very helpful. We were both able to check-in early and to leave our luggage on the last day to explore Athens easier.
The appartement is tiny but beautiful and clean. It is close to the center of Athens so that you can reach the Acropolis for instance.
All in all, we enjoyed our (short) stay at Sokol’s appartement and we’d recommend it :)
