Great location - 5 or 6 minutes walk from either the river on one side and Wenceslas Square on the other side. The flat itself was in a safe and pleasant area of the city. Alina allowed us to drop our bags off early. The flat was very well decorated, modern fittings and clean.
In terms of Prague itself, Google Maps did the job of finding the best transport around the place and recommending the best bars and restaurants. A great city.
100% recommend.
