We spent there 3nights (group of 3 adults and 2y old baby).
Location is absolutely perfect-directly in the city center. There are many restaurants/cafes just a minute walking.
Flat is very spacious, with high ceiling, historical look, but comfortable furniture.
In general we were satisfied but I d like to mention following:
There is a central AC but in living room only, which was really uncomfortable in January (when the temperature was between 2-8C in the night) and it was really cold in 2 bedrooms (we had to use extra electric heater, which helped but it is not very convinient especially woth small sleeping baby in the room).
Flat is rather on the 2nd floor (no lift) and you have to walk app. 40stairs on narrow stairways which might be an issue for some guests.
We had to build travel cot by ourselves as it was not ready and we also missed water kettle in the kitchen.
We had 2times electricity blackout in the flat for couple of minutes during our stay.
