Marco was a great host, apartment was lovely and clean, he made sure the fridge was stocked with a few bits, and met us with even more treats on the first day, he really went the extra mile.
On top of this, he took the time to explain to you little details about the apartment (how to lock the doors a certain way, etc.), and more importantly, tourist attractions and sights around Naples. You could tell he really has a passion for his city, as well as the knowledge to explain the culture in detail. Also, his English is good, better than my Italian anyway.
The desk handily has a tidy pile of tourist leaflets and brochures on it, and Marco himself is full of suggestions, so you'd never struggle to find something to do.
Marco made sure we had his number on the first day, so it's easy to contact him if needs be, be it about the apartment or even any queries about the city. Went as far as to book a taxi for us to the airport on the last day. He's very kind and helpful, top bloke, nice apartment, loved the city, would definitely visit again!
