Unable to answer "Is this place wheelchair accessible?" – Botička Blatnička (Shoe Store) – https://osm.org/node/5035800776 via StreetComplete_ee 61.1:

Im not too sure if this place still exists, it doesnt really look like anything is here anymore, but if you search them up online (e.g. - https://www.facebook.com/obuvblatnicka/) they seem to be active and on this address. Also, it appears to be called "Blatnička" not "Blanička" which would line up with the name of the street (a pun on the street's name i guess), i changed that, otherwise leaving it as it (it could just be a place that isnt really visible/has no sign on the outside)
