These distances are exact, but are based on a straight line from point to point. Actual walking distances will be slightly longer.
I checked in via Cafe de Maria... a nice gent with not much English helped me. Pretty sure he indicated that the rates in Brierley’s 2019 book are several years old... I assume this as I don’t speak Spanish either but he looked at my guide when I ate dinner and he seemed to say that. I paid 30 euros for a private room with a bathroom. Might ask for nonsmoking... I am not really sensitive but my room has an ashtray and instructions. A good place to stay. I would recommend it.
