My friend and i had the best time at this apartment. Absolutely well located in the city center and close to the old town, just as described. You can go anywhere walking, since it is at 5 min from Charles' bridge, by feet. The style of the apartment is a perfect mirror of the city's atmosphere. Nothing to say about the cleanliness.
George has welcome us and he is a great host. A cab was waiting for us at the airport and that made the arrival very convenient. He gave us some tips and suggestions on restaurants, events ... and a very useful Map !
I would definitely book the same flat if i come to go to Prague again !
