Sergio's apartment is a beautifully appointed modern flat in an older building. It has everything you could need including a large secluded terrace garden. We didn't actually meet Sergio but he was easy to deal with via email and always responded quickly. The apartment is a short walk from the Duomo metro and within easy walking of the lively canals area. A lovely friend met us at the apartment and gave us some good local info that helped on our short stay. Many of Sergio's personal effects decorate the flat, making it quirky and fun. Be aware that there are a few stairs to climb to the apartment but we found that a good way to work off the local pasta ;-)
