Excellent stay.
I used to stay at hostels more often in my younger years, but now in my early 40s I more often do not. However, prices in Helsinki lead me to The Yard, and boy am I glad it did.
What a great hostel. Located on the 3rd floor of a mixed-use building, you enter by a shared building entry along a pedestrian street and then buzz into the hostel. Once you're properly checked in you will receive codes to enter the building.
The hostel is social but not loud. The living room is super comfortable, with some conversation and sometimes just people quietly working or on their computers.
Age range varies, probably skewing younger but i was not the only non-20-something there.
I was in a female-only room with 4 bunks (8 beds) in a HUGE room with wonderful light and seating area. Drawers under the beds can be locked, and open cubbies are also provided for non-valuables. Each bed has a curtain to ensure privacy, and in each bed area are outlets, a reading lamp, and shelf. Very clean.
The hostel provides sheets and blankets, though you have to make your own bed. They do NOT provide a bath towel. I found this annoying. Rental was, I think, 2 euros. In my opinion, charge 2 euros more per night and nobody will bat an eye.
Front desk service is super friendly and helpful. I was able to leave my bag in their bag room before check-in and after check-out. Be mindful that no staff is on site at night. Breakfast is provided, and it was basic but adequate.
