Just a misss communication. When I asked him to 1 day extend, Sokol just sent me a link that show me 'agree' to do by system. So i did it, photos of appartment just looked the same and I was thinking its the same appartment.
la voila, actually, it was not the same appartment. so at 14 February, we have to checked out and move to the other place. I was really angry about this, so i asked to cancel.
Why he did not answer, "sorry this appartment was already booked by another person"
