Mattia's apartment is absolutely stunning and has more - and brand-new - comforts than many people have in their own homes - washing machine, dishwasher, hob, oven, microwave, gorgeous pans and crockery/cutlery, 2 TVs with Netflix, double glazed and insect mesh on all windows (plus very quiet anyway), fabulous shower, fabulous huge and comfortable bed and aircon. Wifi was excellent. The whole place is newly and beautifully renovated with Italian ceramic tiles throughout - all sparkling clean, and it is very secure.
The apartment is just near Santa Lucia - one of the coolest areas of Napoli*- so a few steps from the lungomare, and a few minutes' walk away from Piazza del Plebiscito and all the hundreds of other wonders of Napoli.
As a host, Mattia was simply outstanding - he was well-organised, efficient and responsive to absolutely everything I needed to know, as well as being very friendly, patient and attentive. That's all I can think of to say at the moment.
