We had the pleasure of staying at Matteos place for ten days and only wish that the stay would have been longer. We have stayed in Riva a few times and always had good experiences but Matteos place is now our favourite. Super easy communication with the host, the location is really in the dead center of the city, the windows are super thick drowning out all noise of the bustling street outside and there's AC in all rooms.
This is a fantastic place stay!
