My partner and I are renting out our one bedroom apt in the convenient area Kallio during the summer (FYI, Kallio is the most vibrant neighborhood in Finland). The location wise, the apt has all possible connections to navigate Helsinki from tram, bus, metro, so on. It is fully furnished and gets a plenty of sunlight. It's perfect for a couple who needs a place to stay during the summer.
The rent already includes all fees from water to electricity, laundry, internet and insurance; thus, unfortunately, it is tricky to offer you discount.
We have two periods of available time to rent the apt: (1) June 4th-July 3rd and (2) August 3rd-September 20th. The proposed price is for the monthly rent and if you want to stay in a different period, we can discuss the proper price. For more inquiry, please send me a message; so I can answer to your question.
