Yes, the view is of Esztergom on the Hungarian side, taken from midway across to the Slovakian side (Sturnovo).
The river doesn't obviously seem very high close up, but I've no idea what it's normally like. There's certainly a decent current on it.
I thought I recognised it! I was there last week. I also didn't get the impression that the level was particularly high, although in my photos it actually looks a touch higher than in yours.
