    <p>Hi Mateusz & others,<br>
    </p>
    <p>As far as I know, yes, there are actually seperate "staircase
      letters".</p>
    <p>I'm going to cite this article from
<a class="moz-txt-link-freetext" href="https://masodikkerulet.hu/archiv/cimkezelesi-eljarassal-kapcsolatos-kozzetetel-2">https://masodikkerulet.hu/archiv/cimkezelesi-eljarassal-kapcsolatos-kozzetetel-2</a>
      : <br>
    </p>
    <p>"The correct addressing would be this:<br>
    </p>
    <p><strong>1024 Budapest, Káplár utca 4-6. A épület, A, B, C, D
        lépcsőház, B épület A, B, C lépcsőház</strong></p>
    <p align="left"><strong>1024 Budapest, Fillér utca 8-12. A, B, C, D
        lépcsőház"<br>
      </strong></p>
    <p align="left">Based upon this, yes this thing exists.<br>
      Based on that: 1024 Budapest, Káplár utca 4-6. A épület, A
      lépcsőház.<br>
      = 1024 Budapest, Káplár Street 4-6. Building A, Staircase A</p>
    <p align="left">But there are other examples as well. Like at Örs
      vezér tere (Fehér út), there is a big office building, which has
      two staircases: Staircase A and staircase B.<br>
      <br>
      You would see such things like "<span>Fehér út 1. B. lph.", lph is
        the abbreviation of lépcsőház (staircase)</span></p>
    <p align="left"><span>Hopefully my explanation is useful.</span></p>

      <p>Hi Mateusz,</p>
      <p>Earlier I've mapped many big buildings as explained in this
        comment, but as I can see them on the map, they had the
        "staircase letter" as<b> part of their house number</b>. So no
        special addr:unit or other tag was needed. Or every normal
        entrance had their own house number. Examples:</p>
      <p>New building: <a moz-do-not-send="true"
          href="https://www.openstreetmap.org/node/1541562620"
          class="moz-txt-link-freetext">https://www.openstreetmap.org/node/1541562620</a></p>
      <p>Old building: <a moz-do-not-send="true"
          href="https://www.openstreetmap.org/node/1419165875"
          class="moz-txt-link-freetext">https://www.openstreetmap.org/node/1419165875</a>  
        (I make such address nodes part of the building line.)</p>
      (The comment refers to both old and new - so in this area at
      Budapest these are not numbered as the comment explains. However I
      can imagine such house. In that case I would mark the building
      outline with the number (Address) and the entrances just <b>entrance=*
        + ref=* </b>maybe.)<br>
      <p>Another city, same style: <a
          href="https://www.openstreetmap.org/node/6703947891"
          class="moz-txt-link-freetext" moz-do-not-send="true">https://www.openstreetmap.org/node/6703947891</a><br>
      </p>
      <p>I have not seen such "range of flats" marked, as in original
        question. I didn't answer because I don't know if they exist
        anywhere in Hungary. <b>Then how could anybody say such houses
          do not exist?</b> :-) But if they are rare, I think this is
        not a good "question" in StreetComplete. I do not remember
        seeing or mapping such "rage of flats" ever.<br>
      </p>
      <p>Best regards,<br>
