Simona's apartment is an absolute gem. You won't another spot so unique. It was also such an incredibly comfortable spaces, and you can't beat the location. Everything is a short walk in whatever direction you go. The bed and pillows were the most comfortable we've ever experienced from an AirBnb, and the space was decorated with so many personal touches. Simona is also the most attentive host we've ever had. Communication was warm and prompt, and she even sent a detailed, thoughtful list of sights and spots to visit, best pizza places, and Napoli pastries to seek out. We followed her guidance and advice, which resulted in such a full and satisfying few days in Naples for us. She also left plenty of Italian snacks and treats, which just adds to why she is such an incredible superhost.
As far as what is within Simona's control, she was perfect. With that said, what other reviews say about the wifi and noise are true. The wifi signal was so weak that while we could receive and send messages, we couldn't open maps or any browser. My husband and I are working while traveling, and work just wasn't possible these few days, so we took them off. We ended up using data roaming, or would stop outside H&M to use their free wifi when we passed. But that can't really be helped -- weak wifi signals are a reality for bottom floor stone Naples apartments.
And as for the noise, I mean, yeah. It's pretty loud. Even though the apartment is tucked away in side streets, the front door is a pane of glass so motorbikes and voices pass through easily. We travel with a noise machine, and we had that at max volume. The neighbors, and kids running up and down the street, were still audible. And yup, the next door neighbor loves to blast music and have his own karaoke session to the point where it feels like you're next door to a night club. This seems to just be part of the charm of Naples though. We took it all in strides, and the apartment more than made up for any issues with noise or wifi. We would absolutely come back here if we visit Naples again!
