This place is more of a photo studio than a residential apartment. The whole place smells like cement. The host suggested turning on the dehumidifier but that didn't help much with the funky smell. The air conditioning is not set up so if you need to use it you have to leave the window open and stick the hose out of the window, which would allow street noise in and not very efficient.
The bed is not very comfortable as it's a sofa that can be turned into a bed. As I said earlier, if this place was not set up as a photo studio, they could place a comfortable king-sized bed in there easily.
The heat system didn't work and I slept in the cold for two nights, but Markus brought me an electric heater for the last night of my stay.
Markus is a great host though and he was very prompt and helpful in our communication.
