We spent 4 nights at Sokol's apartment, and it was beautiful. The place is stylish, cozy, very clean, and Sokol is very nice, he asked about us all the time, get us a little gift. The street where the apartment is located is not so friendly at first, but you can get used to it, and it's 5 minutes from everything, so it's okay. I'll definitely recommend this place, if you are in Athens.
