Everything was great with this rental. Location, cleanliness, communication (we communicated with Alessandra, Laura's mom). Before booking I was carefully reading comments about any noise issues considering the central location of the apartment in Naples. I agree with most comments that the apartment is very quiet, in fact it is dead quiet at night, after about midnight. You will hear courtyard noises when people wake up or come home but these were not at inconvenient hours at all. All in all we had great four days and nights in Naples, and Laura's apartment and the hosts deserve a five star rating.
Thanks Alessandra and Laura!
