My girlfriend and I stayed at the Santa Chiara Inn for 3 nights, our first stop on our Italy trip.
We had advised the property ahead of time around what time we would arrive and as instructed, someone was there to greet us for check in. Keep in mind, the tourist tax of 3 euros per person, per night, must be paid cash.
The only downfall from this property is that there is no elevator and we knew this ahead of time, and were OK with it. But keep in mind in case you are not fine with no elevator and climbing 3 flights of stairs at 30+ degrees.
Our experience from beginning to end was fabulous! The room was very comfortable and clean. We got great nights of sleep.
Best part, you are so centrally located to everything. Shops, restaurants, the port, the train station!! We walked absolutely everywhere and found great gems, no tourist traps.
Breakfast included was on the same street, you could order the coffee you want and pastry. They were decent but not amazing. However I must admit not being able to find any great homemade pastries in Naples. Seems like the same provider goes everywhere.
We would definitely recommend staying here and would definitely go back if we were coming through Naples :)
