The hotel is easy to reach on public transport.
By rail: From Locarno, take bus 316 (journey time: 20 minutes) to the "Brissago Municipio" stop (a request stop) and from there it is 2 minutes' walk to the Sunstar Hotel Brissago.
By boat: A nice alternative is to travel by boat on the "Locarno NLM" (journey time: from 55 to 80 min.) as far as the "Brissago NLM" landing stage and from there it is 2 minutes' walk to the Sunstar Hotel Brissago.
