The location is perfect, right there is the hill Locus Strefi where you should definitely go up for watching the sun go down! Also the nearby streets of Exarchia are so nice. I really liked the old style of the apartment, especially the kitchen and the big bathroom. We didn't meet Kristina in person - only on the phone, but she seems to be a nice, helpful and friendly person. All in all it was a nice time we had, thank you!
