I wouldn't describe this as a "luxuray flat". It had basic things but there was no handsoap for example (given covid this seems a necessity). Communication was good but I was asked the same questions about check in multiple times even when I had answered. This wasn't a super clean appartment - it was dusty, stained sheets and there was hair in the bathroom but it wasn't awful and managable for a few nights stay. The host was a bit slow to respond about a blocked sink but it got sorted. The area isn't amazing in Naples but handy for the train station and transport in general!
