"Quirky" is a word that comes to mind, but I'm hesitant to use it as "quirky" can be used as a codeword for "chaotic", and this wasn't the case at all: the apartment was well-presented and clean, while remaining very characterful. In fact, it was possibly the most attractive Airbnb I've ever stayed in. As a bonus, we were permitted (on our request) to enjoy the company of the lovely family cat! Giovanni was a resposive and helpful host, a pleasure to deal with.
