Josef's apartment is great. Location is exeptional you can easily get everywhere within Old Town in 10 min. Room was big and well equiped. First time I see when the room in reality looks exactly the same as uploaded pictures made by professional photographer.
Josef is a very helpful and polite host. (Top 1 so far in my rating based on Airbnb experience)
Long story short, 5 out of 5 stars well deserved.
