We had such an amazing stay in Barbora's apartment!
The flat is freshly renovated, with all the equipment needed ,very well located in Praha center, you can visit everything by foot.
We saw Barbora's boyfriend Radek who was so kind and helpful, he kindly accepted us to stay in the appartment until late evening on the last day (late flight at the airport)
So I can only recommend to stay there ! And for sure if I'll come back in Praha I'll know we're to stay ;)
