The only word that comes to mind is "perfection". We won't stay anywhere else in Prague again. The location is superb with easy public transportation connections. The view is to die for, and the decor and appliances are simply the best. The owners are very helpful and responsive. We enjoyed every minute of our stay there.
Some details of the apartment's accessibility: It is located on the top floor (European 5F). Although there is a lift, it only goes to 4F. You have to walk up 24 steps from 4F to 5F. In addition, on the ground floor, there are 4 steps up to the lift landing. It wasn't a problem for us, but may be something worth noting.
Lastly, thank you, Michal&Michal, for making this lovely apartment available.
