Unable to answer "Do these steps have a handrail?" for https://osm.org/way/149468197 via StreetComplete 53.0:

The stairs are in a totally different position. The current OSM map shows stairs on the pavement between the guardrails and the parked cars. But that is just a normal pavement.
However, there are stairs leading from the pavement down to Museo Francisco Sobrino (no guardrails, 8 stone stairs, upward direction toward the street).
