For the most part, I enjoyed the stay at Alex's and Kate's place. It's very nice and looks exactly as in the photos and the location is relatively close to centre of Prague. However, my issue was a constant noise that sounded like a washing machine was on 24/7 on the floor above. I'm not sure exactly what it was but it was often hard to sleep because of it and it did not get resolved. At first, when raising the issue, Kate did not seem to take it very seriously but when I pressed her, she said they will try to send a technician over to the building. But I haven't heard about it afterwards and the noise never stopped. But otherwise, I really liked staying in this flat.
