The apartment was actually smaller than I thought. It had low ceilings, especially in the bathroom, there I had to bend to stay (I'm 190cm). Other than that, it's nicely refurbished and looks new.
The location is good. It was quiet at night.
The communication was bad, Stefan was unresponsive, he didn't care, it took him about a day to confirm he would meet me at certain time, when I was already in the middle of my flight there. Then right away I discovered the internet was off, and only on the next Stefan announced, it would take 24 hours to fix it, when I would be already away.
