Small studio flat with living space (bedroom, kitchen, dining room) and bathroom. It's like a large hotel room with sufficient appliances to be fully self catered. Very clean, and everything works seamlessly. The new 15 light rail / tram links it very well to the wider Helsinki public transport network. The 6- route of buses goes close by too.

I thought the pillows were a bit thin and the mattress could have been a bit better but I slept well. I often do find thin pillows in Finland, though, so it is probably not specific to this accommodation which I did enjoy.
