We had a very pleasant experience staying in this apartment. We were there for two nights (4 of us) and had everything we needed for a comfortable city break.
The location is super central, the space is airy with gorgeous high ceilings and the beds are comfy too. The bathroom has both a shower cubicle and a bathtub and there is also a bidet.
We had to go collect the keys from the office which was not too much of a trouble as this was very close to where we were staying.
The flat faces an inner courtyard so sometimes the neighbours might be up late but shutting the windows did solve this for us. You also get a 24/7 mini market next door and a traditional Czech pub just across the street. Sweet!
