We had a fab time in Prague, made better by the accommodation.
The flat is perfectly set up for a travelling couple. Small kitchen with everything you could need, nice big bed (actually a king, powerful shower, fluffy towels and all very clean. Although if you like to sleep in the dark take eye shades as the blinds let a lot of light through in the mornings.
The flat is in a great location for sight seeing, everything is walkable and on rainy days we grabbed an Uber. There is a lovely craft beer bar just one street away (Gulden Draak) which is well worth at least one visit. Also a bank at the end of the street and a little supermarket.
