Serena’s place was gorgeous and she was very responsive.
We had small issues with the heat and gas going out one night and it got fixed around noon the next day - it’s an older building so that sort of stuff happens and Serena contacted a professional to come in as soon as possible.
There was also some construction in the courtyard where the unit is and we were woken up by drilling at 8 most days so you might want to contact Serena to see if this is still going on (or pack earplugs!) but this is obviously a more temporary issue.
Otherwise the place was very spacious and very close to the Duomo and other great places!
