Sarka was so nice and the listing was beautiful! My dad and I stayed for a vacation for a couple of nights, and it was in an ideal location. The only thing is that if you need to open your windows for air flow, it is very loud with the buses and with people walking and singing/laughing/etc essentially all night on a weekend. If you have the windows closed it is not an issue at all.
I did not specify that we were going to sleep in two different beds, so only one was prepared, but it wasn't a problem at all, as there was bedding available! There is no AC, so just be mindful if you go during warmer times, although the windows do open and that helps a lot. The coffee machine is a dolce gusto (I believe) and there no coffee provided, so if you're like me and want to bring some coffee with you, Nespresso pods won't work.
The apartment is very large and comfortable. The living area is great! We did use the washer for some clothes and it worked beautifully and there is a rack provided to hang dry your clothes. There is a fan in each bedroom as well. Overall, we had a great stay and would highly recommend it! Prague is a beautiful place :)
