This was a building in Budapest, "P" stands for "pince", as in basement, "FSZT" is "földszint", literally "ground floor", "MFSZT" is "magasföldszint", "high ground floor" meaning mezzanine level, and "1E" is "1. emelet", "first elevation", so that was highest.

The quality of the elevator still made me think of taking the stairs though.

Fun fact, Hungarian is the only language I've heard of that uses Latin letters and also has multi-glyph letters as long as four glyphs, so "sz" is considered one letter like in Polish I think, but "ddzs" is also one letter.
