Very nice apartment, big rooms, comfy beds, not so comfy sofabed/sofa.
Large new beautiful bathroom with shower and bathtub. Heating worked fine in the entire apartment.
Fridge was sometimes loud at night, doing a rhythmical buzzing sound.
The entire building is beautiful and makes you feel like in a different time. Downstairs is a very very, nice café and a bar in a cellar, spectacular!
Location more than perfect and I'd definitely book again!!!
But mind: We only got one set of keys in the beginning, although after asking for a second set, Jaroslav dropped one off straight away.
Next thing guests HAVE TO KNOW: The front door (the one to the street) of the house is locked at night, before the café downstairs opens in the morning. That door only opens with a key.
So one guy was trying to leave for the airport one morning and had left their key to his roommate. After coming down from the staircase, the door locked behind him. The front door was closed as well. So he was trapped. He had to bang on the door and scream and shout loudly before I opened. Also this is really dangerous in case of a fire! It should be solved.

Apart from that, it was a great experience and I'd definitely book again!
