The mattres is horrible, my friend slept in the floor and me in the sofa. Also the appartment is too full for the size, it is a bit uncomfortable, there is not cooking knife and a chopping board in the kitchen, and no rubbish bin.
We heard a bip noise all the time including at night, which didn't let us sleep well adding that to the bed situation. The appartment has two windows leading to an interior patio so no day light gets in ever and it is hard to ventilate. Overall unconfortable.
