I have used them once and the service was really good. It's BWP650 per person (not as cheap as public transportation), but it is worth it for the convenience. The van is new, the driver is responsible and our trip went smoothly. I haven't found any public service that does this route directly, so this van is an excellent alternative. I am actually using it again next Friday, so if anyone wants updates let me know and I'll write them here later.
Tip: it's a small company, so they don't run if there are no bookings for the week. Call them in advance to make sure the service will be available.
