John Wesley on Acts 28:15

The brethren - That is, the Christians, came out thence to meet us - It is remarkable that there is no certain account by whom Christianity was planted at Rome. Probably some inhabitants of that city were at Jerusalem on the day of pentecost, Acts 2:10; and being then converted themselves, carried the Gospel thither at their return. Appii - Forum was a town fifty - one miles from Rome; the Three Taverns about thirty. He took courage - He saw Christ was at Rome also, and now forgot all the troubles of his journey.
