Okay, where do I begin?
Casa Mamelu is...perfect. Francesco is the best. Napoli is fantastic. Now onto the details:
Location: 5min walk from Mengellina Station (direct train to Salerno - if you're going to Amalfi Coast), 4 stations away from Garibaldi Central Station. 10mins from the promenade. 30mins walk to the center. The best coffee in town (swear!) is just downstairs to your right. Have it every day and have it plenty. Make sure you walk up the hill (to your right looking from the balcony) to experience the best view of the gulf and the city.
The apartment: just perfect. The best I've been to using Airbnb. Ambience is just right - something about Casa Mamelu makes you sleep like a baby, it just feels like home. And the view...oh boy, that view. I was waking up every day to see what colors the Vesuvio would wake up with.
When you top it all up with the host like Francesco - you just don't look any further. He's more like a friend than a house owner. He picked us up from the airport, dropped us off - and In the meantime packed our brains with the info on Napoli and Italy (and his cats, too) we wouldn't find in the books.
Thank you, Francesco, and hope to see you again!
