Emergency line 030 — 75 43 73 44“Nicola fully restored our La Marzocco GB5 after 12 years of daily service. It runs better now than on delivery day. On schedule, fair prices, honest advice.”
“The Slayer died in the middle of the breakfast rush. Called at 8:30 — by noon Nicola was at the door. Gasket replaced, everything calibrated, back in business. That's what emergency service looks like.”
“I brought in my 1965 Faema Faemina for restoration. Six weeks later a different machine came back — completely overhauled inside, original patina outside. Exactly what I wanted.”
“An espresso machine is not a kitchen appliance —— Nicola Maisto, owner of 9bar Studio
it's a pressure vessel with standards.”
