This place is LOUD. Really, really loud.
The apartment is on the top floor, and a strange acoustic effect means every time a tram or car goes past outside (between 7am and 11pm, every few seconds) the wooden ceiling creaks, wails and groans like it's in a storm. Incessantly. The host clearly knows this, as there's white noise machines and earplugs in every room, but it wasn't enough to block it out.
It's a shame, because everything else was exemplary. Great communication, spotless place, comfy beds, great facilities, nice little coffee machine, affordable and perfect location. I'd say if you can handle noise, go right ahead. If you're even a little bit sensitive, give it a miss.
