Pretty exact [ANSWERED]

This is going to be tough be warned.
So today I took a nice quarantine walk and found one of my favourite types of puzzles in the street.
I took some photos and made some measurements on Google Earth and the distances are pretty exact.
To start with I already indicated roughly in which part of Budapest I live: it is South Buda




Unfortunately, this is something new so it is not on Street View but I could identify the lamp post especially the small brown plaque with number 91


SV please

not that precise:

I live around here:

47°23'42.20"N 18°59'36.42"E

And I usually don't walk more than an hour which is only about 4-5 km for me in total so you should look for this distance pole in a circle of 2.5 km only.
But actually knowing this location, the thumbnail map is a bit of a spoiler here.

Thanks for the clue and the inset map definitely helped!
