Marcello is great host, he replies immediately to all our questions. It was very nice of him to leave chockolates for kids (and there was even nesquick for morning cacao :)).The place is like in description, everything is new and it is really clean. It is close to underground and walking distance to historic centre. Around are restaurants with delicious Neapolitan cuisine. The only flaw is that it is not quiet, but what else you could expect if you stay in the Heart of Napoli :) (actually I do not expect one can find quiet place in Napoli).
