Yes very much so. They were very welcoming and helpful. Their apartment is on 3rd floor and unfortunately we had lot of luggage with us but both brothers helped us with our luggage, gave a tour of the apartment, helped us with map and what to see and how to get there etc. They even offered us a pizza as we reached late at night.
The apartment is nice as well and very close to places, especially the port. We walked to get ferry to Capri.
We were looking for someone to take us around Naples, Amalphi coast and Pompeii. Their dad did this for us and he was so nice to plan our itinerary and show these places as locals would do. Took us to best sorts and patisseries for breakfast etc. If I ever go back to Naples, I will stay with them even though I have to climb 3 floors :).
