I need an extra bed.
ag-GIUN-to — three syllables, stress on the second. Double 'g' gives a longer sound.
When you are checking in with a child or an unexpected extra person and need an additional bed in the room.
'Ho bisogno di' (I need) is the standard Italian expression for need — literally 'I have need of'. It is followed by a noun. 'Letto aggiunto' or 'letto extra' are both used. This is more formal than simply saying 'mi serve un letto'.
C'è posto per un bambino?

Do you have a baby cot?

Many Italian hotels can accommodate children under 12 in the same room as parents at no extra charge or at a reduced rate. Always ask about family rates ('tariffe famiglia') — they are not always advertised.
