Klara's apartment is an excellent place to stay for a short break in Prague. It is situated only 2-3 mins walk from Charles Bridge and 5-10 mins from Old Town Square & Astronomical Clock. Position-wise, we could not have asked for a better place to stay! Klara was fantastic at communicating prior to our stay, answering any queries we had very speedily. Check-in was a breeze - Klara was very flexible and actually let us leave our bags as we arrived straight from the airport at around 12pm (well before her usual check in time of 3pm). This was much appreciated and allowed us to explore Prague on our first day without dragging suitcases around with us! Klara's apartment also had a wide range of recommendations and pamphlets that gave us some excellent tips and places to visit, and her local knowledge was invaluable in helping us plan our time in Prague. We would thoroughly recommend Klara's place as a central 'base' to stay for a short break in Prague.
P.s. If you are a beer lover - check out U Fleku (about 10min walk from Klara's apartment; it's been around Prague since 1499!) - the beer and food is excellent, live entertainment provided whilst you enjoy a plate of Goulash and a pint of their excellent dark beer!
