The apartment was just fantastic. Even better than we expected. There was HEAPS of space and the staff were incredibly helpful and friendly. Wifi was strong and the whole apartment complex was clean and well maintained. It is a good 15-20 minute walk to the city center, but totally doable. Otherwise, the metro is right around the corner and it is only 3 stops to the old square.
I will definitely book here again when I return to Prague.
