The apartment was clean, comfortable and well equipped. Bed was huge and really comfortable, shower felt luxurious.
It is a little way from the centre (3km from Old Town square) but the metro is very easy to use and you get the benefit of having some excellent cafes and restaurants on your doorstep. Štěpán and Petra have produced a great guide to all their favourite local eateries.
Would definitely use their place if we visited Prague again.
