I stayed in Mariella's home for 1 week with my family. Flat is very modern, cleen and has everything you need (i specially want to notice kitchen with a cofee maschine and washing maschine). It's very close to the train/metro station Margelina so it's very simple to rich every place you want (and cheaper than to get a taxi) and has a great supermarket at the corner of San Filippo street (so when you are tired after Capella San Severo-must see in Napoli, just take a 3.50 euro Falangina and a good piace of parmegano :))) with strawberry). And, of course, there is WiFi. Mariella got us all the information we needed and was very attentive to our needs (for example, we travelled with a baby so we needed a baby-bed). I absolutelly recomend Mariella's home to visit Napoli.
