Giulia was very helpful, and was mostly very attentive to our enquires. She replied very quickly to our messages before our check-in, and was very nice when we had questions about the premise (and even when we asked her about where to get gelato!).
The apartment was to a large extent very close to its description. It's got an artsy design, and looks very good on pictures! The outside of the apartment may seem a bit dodgy but once you're inside it feels better.
We were quite unlucky because when we stayed there the hot water supply was rather unstable. Not only was the water not quite warm enough (it was about lukewarm), it was also a bit on and off. We therefore didn't get to use the bathtub. I contacted Giulia immediately about the issue (at about 9pm?), and she got back to me at about 1am. It is understandable as I know she was away from Milan that day, and she promised to investigate the issue the next day. The water continued to be barely warm enough for a shower the next morning, so I contacted Giulia again and asked her if it would be possible at all to ask for a part refund, as we did not get to utilize all facilities in the apartment. Giulia replied quickly and said that she had investigated the issue after we checked out, and to her the water seemed warm enough and therefore she believes that it wasn't a problem of the hot water supply but simply that I'm more used to water that is hotter.
Having lived in different properties and different countries in the past few years, I personally don't think that is the case - I am usually the one complaining to my housemates that water in our house is too hot! Though I do appreciate that Giulia has attended to the issue very quickly. Hopefully it was just us being unlucky - the hot water supply just decided to be unstable during the time we were staying there, and future Airbnb guests won't experience the same issue again.
