Daniel greeted us with a warm welcome and took time to explain how to use all appliances.
The location is not exactly central, and is in an alley, but it is not difficult to access the metro (no lift) or to hop on tram 28, we even walked to the castle from the flat (about 40 minutes with young children).
The flat exceeded our expectations. It was very comfortable (i guess over 120 m2), great A/C, comfortable beds, and all modern touches. We actually didn't want to leave!!
