The whole check-in procedure was easy and Melanie was very responsive. The apartment is centrally located which was perfect for our first visit in Naples.
One thing to note is that the room for the third person (we were travelling in three) had to sleep in the living room which is not air-conditioned. Noisy is another issue, but that may not be avoided in city centre. The staircase in the building is sadly shabby and wrapped with spider nets, if that would be an issue for some travellers.
Other than these, our stay was okay.
