I stayed here for a conference held at the main campus of the University of Helsinki, and it was the perfect location. Less than 50 metres to the meeting rooms. Breakfast was good but seemed disorganized at times, especially when it was busy -- most mornings I had to remind the staff to bring coffee, as they tended to forget. Luggage storage on arrival (until the room was ready) was not properly secured, which was a bit worrying but turned out OK. They don't do housekeeping unless you ask for it -- they didn't tell me that at check-in -- but I eventually asked for every second day and that was just fine. The location for much of downtown is also good, good selection of restaurants nearby as well
