There is a 140cm wide futon bed in the bedroom, and a separate living room/kitchen area. The bathroom is small but has a shower. There is a short walking distance to the biggest beach of Helsinki, and nice walking paths as well. You will reach the very center of Helsinki within minutes. I have two cats, who are staying at my place part time. I always clean before guests, but if you are VERY allergic, you might wanna think about choosing another place to stay.
