We stayed here for five nights and I can't praise it more highly. The owners Gabriele and Manuela are the perfect hosts and they live on site which is very helpful if you need assistance or advice.
The rooms are gorgeous - modern, beautifully decorated and very, very comfortable. The bathroom was massive with a good sized vanity unit (great for all my makeup and hair tools), a lovely shower with good hot water and water pressure and lots of clean, fluffy towels.
The room even had a small balcony which was high above the street and looked over the grand buildings of the Santa Lucia district.
The breakfast is beautifully presented - but mostly sweet things like croissants, fruit, sfogliatelle and cereals. Some cheese and ham would have been a great addition but this is a minor gripe in the scheme of things.
The wifi was free and fast as was the television - we loved the MTV! - and the location was perfect. You are minutes from Piazza Plebescito, Via Toledo, the historic centre, the port and the beautiful Lungomare waterfront area.
I would not stay anywhere else in Naples - Orsini B&B was perfect.
