Unable to answer "What’s the surface quality of this road here?" for https://osm.org/way/188122185 via StreetComplete 44.1:

Surface in the plaza San Marcelo is like pebbles (see image). Also, is this the correct way to represent a square? I would use an area. But I'm new to OSM. I'll check the wiki with time.
