We arrived very late in the pouring rain in Porto but Mario was still available to give us a friendly welcome and quick tour, and his communication in general is very good. The apartment is definitely 'cosy' (as expected) but is very well fitted out with a powerful shower and a fantastic view over the city - just what we needed as a central base to explore the old city, and only a few minutes walk up the hill from Sao Bento train station. Certainly would recommend!
