We stayed at Alessandro's place for 3 nights and really enjoyed it. Location is great, easy access to public transport to get to main sightseeing spots in town, but also just a lovely local neighbourhood to explore anyway with plenty of cafes, restaurants and shops around.
Alessandro gave us good instructions on how to get to the apartment, but if you're coming via public transport I'd still recommend have google maps / citymapper on hand to help that first time you arrive!
