Good stay in Naples :) The area isn't the best (central-station-district, a bit rough and dirty) but it's okay and there's plenty of great Pizza in the area. The place itself does the job. The kitchen isn't all that well equipped, so it's not suitable for a lot of cooking. The flush of the toilet was a bit unnerving since it's super weak and uses a special kind of system - it seems to get blocked easily and in this case makes the apartments unusable + it'll cost you 400€. Luckily we didn't experience that during our stay but that's was it's says in the bathroom. So keep that in mind.
Roberto was a great host and very responsive! There was little present when we came in. He even offered to get us some medicine, when we got a bit sick during our stay. Thanks for having us!
