Positive: Location, staff friendliness and cleanliness.
Negative:
No taxi to hotel due to pedestrian area; 100-200 m to walk on rough cobblestones.
No reception area (only a loosly marked wooden door and an unmarked bell to ring; the reception a 4 sq. meters, consists of stairs to 2nd floor and a small desk);
No elevators;
No air-condition;
Breakfast is 4-500 meters away (and is NOT as luxurious as the pictures would like you to believe);
Windows opens to very narrow back yard (2 meters), where your Czech neighbors is watching late night television with their windows open (and cheering and clapping(!) loudly), dog yapping and doves cooing and flapping all night. Yes, you can mute this somewhat by closing all windows, but remember: no air condition;
Small bathroom (but new and clean), but shower door can only be opened half way due to sink stopping it, and you have to squeeze in between the door blade and a very misplaced towel rack.
All in all :Not nearly what we expected at the price.
