Marek was a wonderful host who really knows how to welcome his guests. Very good communication before we arrived and when we arrived at his wonderfully located flat. He is a local so he will give you very good tips about the city (ask him about restaurants!).
The flat was super clean and nicely decorated. It's basically a home so you will just have to open your suitcase and feel like you never left yours, only the city changes! So get ready to explore!
