How to reach the Hotel?
By train: (taken from sbb.ch and google maps directions)
The city close to the Hotel is Lugano, which is well connected by train from all over switzerland.
Once you reach Lugano main station, you need to take train # S60 from Lugano FLP (you need to come out of the station and walk to the right for 2 min or so) towards Ponte Tresa and get down at Magliaso (not Magliaso Paese). Train S60 runs every 15 min. (https://goo.gl/maps/eeBK188Y7ZQ2)
