Lorenzo's little apartment is really delightfully done with the mezzanine bedroom on the upper level and the kitchen and living space below. Lorenzo was helpful and always quick to respond to any questions. Although Lorenzo had quite basic English we made good use of Google Translate and managed very well. The apartment is a 15 minute bus ride form the centre and we easily got used to where the bus stops are and how the tickets work. We went into the city in the morning and returned in time to eat at one of the many delightful restaurants in the neighbouring pedestrianised street. Cheaper than eating in the centre and really good quality. So we did not feel the need to buy any of the multi journey tickets as we would not have had the use of them. Each bus ticket costs €1.50 ( get at any Tabacchi - big white T on the sign) and will cover any bus journeys made in the next 100 minutes - changing bus if needed. We walked a lot around the city and made use of the hop on hop off bus to get orientated. Had a lovely 3 days holiday.
