Pretty much DIY experience.
The host relies on guests to clean after themselves, maybe that's why I had to sweep the floor right after arrival, especially under the now-defunct central heater. Had to remove mould on the wall above shower head holder. Shower itself has very small amount of hot water storage, enough only for a couple of minutes, so if you are not alone, your showers are two hours apart to let water to warm up.
The bed is quite creaky, so neighbours will know exactly how long you last.
The main reason for this is the first perpendicular beam, which is connected to the main beam by means of a quite flimsy metal corner, rather than lying on it, as the rest of the perpendicular beams. Also, the mattress on top of it lies not on a slatted frame, but on a set of four-by-fours, so in the morning you wake up 20 cm further from the headboard, your pillow behind the mattress, and your neck hurting.
And main thing - it is 6th floor of VERY steep and narrow stairs.
