There are more routes to get to Terricciola and therefore you may well follow the directions with Gps. I can try to suggest the easiest route. If you drive along the Fi-Pi-Li take the exit for Pontedera. Then directions to Casciana Terme. When you arrive at La Capannina , turn left for Soiana, Morrona, Terricciola. Just arrive in the village of Terricciola go along Via Roma and park your car in Piazza Giacomo Matteotti. On foot enter in the church square. Just to the side of the church you will see a small archway that introduces you to Vicolo Torto street No. 13, A Casa di Titta.
