Unable to answer "Is there a pavement along this street?" – Travesa de Santa Marta de Abaixo (Residential Road) – way/141431142 via StreetComplete 63.4:

No pavement, but next to no traffic, perfectly fine to walk on the street (possibly safer than on many sidewalks, as there are no garage accesses). I.e. I don't want to tag in a way that discourages pedestrian traffic. (Actually would encourage it)

This is wrong. There are two parking spaces. The one to Ramon Gonzalez(mapped) and San Lazaro(unmapped) with gravel is not connected (for cars) to the asphalt one San Lazaro(mapped) cortezon.
By foot they are connected (and I wonder if cars may move across during market)
