Jana's flat is definitely great for two people visiting Prague. There is an underground and tram station nearby (it takes ~10 mins from the central train station to get there), a shopping mall with super market open until midnight, and - for us very important - it is calm inside with a nice balcony to the courtyard. Public transport in Prague is cheap and well organized, but if you prefer walking, it will take 30 - 40 mins to reach the old city of Prague. The desription given by Jana is absolutely accurate, and communication with Jana before and during our stay was easy and always helpful. So, we definitely recommend Jana's place.
