Karolina is really helpful guest for travelers.
All restaurant and places she had recommended is more than great.
Currently, bathtub has no curtains nor glass-door & no sink at the kitchen. But I heard these two things would be changed, soon.
I think these things would be getting better soon.

Only 5-7min to metro by walk. 1 or 2 station to Prague castle. Many good food places near Karolina's.

If you don't have to cook, I definitely recommend this place!
