I had a nice stay at Helen's for a week. The apt is great for transit to the city center, is close to parks, and has a nice view of trees and birds from the windows. It's on the top floor and there's an elevator so that's very convenient. Two things I would note is that I think the shower might be a bit tight for taller and/or wider people, and that as other reviewers have noted it gets quite warm up there, which is great when it's chilly but not so great when it's warm. Helena was responsive and very kind; she let me leave my bags for a few hours longer so I wouldn't have to drag them around before my afternoon train.
