I booked on a short notice and had limited options in Prague. So I stumbled across Sarka's beautiful flat. The flat is not only really clean, with a modern bathroom (amazing shower) and small kitchen, with all utensils you'd need, it is also located perfectly. If you're staying during december, there is a small christmas marked right in front of the mall, 2min by foot from the front door. The mall provides you with everything needed. There is a metro and tram stop caled Andel only a minute away from the door, which will take you to the city center or the prague castle in around 20min, without the need to swap trains.
Definitely recommend the flat, if you're in Prague over the weekend. :)!
