A nice basic small and clean room in Ikea style. The bed was ok but the pillows were bad, flat and hard. In the apartment there's a convenient common space with washing machines, a kitchen with a big fridge, a dishwasher, cups and plates, etc. - a lot of useful things. You need to leave the room and make a few steps in the common corridor to your private bathroom (right in front of the room) which is quite spacious. The building is situated in front of the central train station with its square, so the view from the room is great, but there's constant street noise. The location is super convenient though. The most disappointing thing was air conditioning - it was cold and blowing super strong right on the bed, so we would sleep under blankets with improvised scarfs (in July) and still wake up with our throats completely sore. The host told us we couldn't fix that as the AC was centralised.
We didn't have problems with the virtual keys, they were convenient to use.
