Hi All Due to a change in

Hi All Due to a change in circumstance, me and my wife are looking to visit Lucca next week for approximately 4 weeks. Looking for somewhere cheap to stay as planning to buy a property with the view of setting up a B & B.With this in mind a.) Can anyone recommend affordable accomodation?b.) Looking to make some solid connections. Wishing to share a coffee/have a chat with as many locals and ex-pat residents as we can. Where/who should be our first port of call without being overly pushy?Look forward to your replies!
