The apartment is fine and actually quite larger than the pictures indicate. However, it can be quite loud at night as other reviews indicate. There was also no cleaning service so it's not ideal for longterm stays. The host is also very slow to respond. I tried to see if I could negotiate getting out of the apartment after seeing the negative reviews and the host just didn't respond for nearly a week until I contacted airbnb support. The internet also went out for almost 2 days and host was slow to respond, but the issue was fixed.
I basically live out of airbnbs full-time and generally leave 5 star reviews, but just couldn't do it for this one. I wouldn't stay with Domus Sicily again because there are a lot of great hosts on airbnb and this just wasn't a good experience, but I think a lot of their reviews on their other listings reflect that.
