The check in was arranged through WhatsApp, and was smooth. The room had been renovated, and was clean and comfortable. The soundproofing was effective - the Via Bologna under our balcony was crowded with stalls and was quite noisy during the day and evening.
The first breakfast was very good, but on the second morning, several items we requested were not provided. After asking the maid, she indicated that some were not available, but others were provided on request. There was a language barrier, but that did not explain why the breakfast order was not completed.
Also, we needed to obtain cash to pay the tourist tax, which was inconvenient, as we used our credit cards for every other expense on this trip.
These hitches apart, the stay was excellent value for money, and the location close to Napoli Centrale station is very convenient.
