Francesca was very kind, we arrived a bit late in the evening and she waited for us. Communication with her was very efficient, she responded right away, also her mom was very attentive, she brought us clean towels after 3 days. The accommodation was very clean, modern and nicely decorated. It's in a central location, close to the "Universita" subway station, there is also a bus station near from where you can take different tour buses to visit Naples or the Amalfi coast. There are also a lot of attractions within walking distance.
We appreciated the breakfast, but since we stayed for 6 nights, it would have been nice if it were fresh. We received the breakfast for the whole week on the first day (2 packages of croissants, toasts, jam, nutella, a carton of juice, one of milk, 1 bottle of water, cookies, coffee, tea - things you buy in the supermarket).
For those of you who plan to stay more than 2 nights take into consideration that there is no window in the room, since the apartment is on the ground floor; you can live the door open when you're there though. Also the wi-fi was very poor, there was no router just a hot spot, to give some examples: to update an app it lasted 20 minutes, to upload pictures 10-30 minutes, we had to connect and disconnect often. We also had issues with the phone signal in Naples in general. The boiler in the bathroom is a small one, sometimes it doesn't last for 2 people, you have to wait until it heats up again.
A recommendation for the host: some hangers would be helpful for the jackets and shirts. In the "amenities" section these appear, but there weren't any in the apartment. Also a trash bin in the bathroom would be useful.
