We can fully recommend staying at Lucas Appartment, it's such an amazing flat, which is beautifully furnished and it's easy to fall in love with the interior.
There is everything included you can think of, a fully equipped kitchen and cosy bed and sofa.
The location is perfect as well, there is metro station Materdei very nearby, so that everything is in 15 minutes reach, also walking into the city center is quick and easy by simply walking down one street.
Luca was a great host, very helpful and hospitable, he had great recommendation and answers immediately if you contact him.
We could not name anything to improve, it was an amazing stay. We fell in love with Naples and the surrounding Amalfi Coast, we hope to come back soon.
