We completely enjoyed our stay at Karel's place. It was as advertised: spacious, comfortable, sparkling clean and all the conveniences. Very good appliances. The living room furniture is a little different than shown, but all very comfortable chairs and sofa. We appreciated the charming homey touches in the decor.
It is magical to see Prague castle every morning and evening from the terrace, and we enjoyed as well the penthouse view from all of the many windows. Distances across Prague are long, but the apartment is situated to be able to walk easily to both the train station and the old town, with the castle quarter a somewhat further but interesting walk away.
I am a little picky about beds--these were all decent and there was some variety in the mattresses so we had an allowance for different needs. We appreciated that there were extra sheets and plenty of extra towels.
Karel and Simon were very prompt and responsive hosts. In all it was a very civilized and relaxing stay.
