Brilliant location right by a train station- 15 mins to central Helsinki, 30 mins to the airport, and a 24hr supermarket next to the station.
Apartment was clean and comfortable, modern decor plus a dishwasher and washing machine.
Three of us fitted in fine.
On the negative side, I was too warm- we couldn’t make it cool enough and it wasn’t stupidly hot out. The windows didn’t open either, so the air was quite drying.
‘Reception’ is a key code for the door, and a combination code for a key box, so no physical service, but it wasn’t a problem.
I would definitely stay here again, without hesitation.
