Another pleasing Civil War item from the Crimea

I make no excuse for showing yet another Civil War item from the Crimea, as they are so fascinating and so scarce. This is an October 1919 postcard from Dzhankoi to Simferopol':

Slightly overfranked since the correct rate was 35k (and the 5k postcard was still valid for postage, as shown by some 1920 items), but utterly non-philatelic. Addressed to a Irma Ottovna Zeel (clearly a German, as borne out by the text of the reverse), but I'm stumped by one line in the address, just before the name of the addressee: "Neft Poosa" is my best guess...? Anyone? Help?

Edit: Pavel Pavlov points out that what I misread as "Neft Poosa" actually reads "kvart Grossa", short for "Gross' apartment".
