No idea about instructor standards at Helsinki as we took our own but everything else is a dream compared with other sims. Good connections to Helsinki, sim close to the airport, great hotels minutes away from the sim with complimentary taxi. No Sesto security hassles, well maintained sim, comfortable, quiet classrooms and good instructional aids, pleasant, helpful staff, free food, coffee and soft drinks, comfortable waiting lounge, good availability and slot times. Cannot praise it highly enough.
