A couple years ago I had a post 'Helsinki City Apartment Bathroom' noting how small the bathroom in my Helsinki rental apartment was. Well, that bathroom was roomy compared to the closet of a bathroom I have in my current apartment. One thing to keep in mind when looking at these photos - the bathroom is SMALLER than it looks in the photos. It is so small, you can't turn around in the bathroom.
Oddly enough, this is a very roomy apartment. We are in downtown. Have two bedrooms and a large shower room.
See here 'Helsinki City Rental Apartment - Photos' for photos of my downright favorite rental apartment. I'm not completely sure, but I think this might be the second best rental apartment. Anyway, if you ever plan on staying in Helsinki for a week or more, you should consider rental apartments as an alternative to a hotel, especially if you are traveling with children.
