Estimated height at which all this happened was 80m (~250')
The accident site is about 2 km from the threshold 18R. As near as I can make it on the approach charts, the aircraft should have been at a little more than 355 feet altitude over there. Threshold elevation is -13 feet, and most roads in this area are a few feet elevated above the fields level. Plausible.
maybe doing a visual?
No way. Not at Schiphol airport. Not when it's busy. Not considering the viz and cloudbase today. Not at 18R, particularly not considering all the noise restrictions. At Schiphol, vectors for the ILS are the norm with intercepts at 2000' (3000' at night even). At the place where the crash took place, he should be firmly established on the ILS. He could not and should not be turning at all over there, other than to maintain the localizer.
The only exception to this is light GA landing VFR at 04/22 which they clearly weren't.
