The rooms: Welcoming and friendly staff. Very personable greeting and check-in with Francesco . Excellent room which was quiet and clean (Deluxe with balcony). Simple yet plentiful breakfast, served by a lovely lady with a smile. I would suggest that the entrance from the street to the premises could be improved to reflect the quality of the interior.
The city: Napoli is an unforgiving city and will be a challenge to some visitors from the UK. However, if you look beyond the noisy streets, you will discover a wide array of beautiful (yet tired) buildings, history, and good food.
Further afield: some of the real gems are situated outside Napoli. For this you need a car and the patience to deal with the aggressive drivers on the road. Sorrento, Positano and Amalfi are great places to drive through, especially along the coast. Vesuvius, Pompei ans Herculaneum must be visited.
Would I visit Napoli again? Despite some of its obvious challenges, I would visit again and I would certainly stay at The Grey. To Francesco and the team, thank you for making our trip a pleasant one.
