Erich's apartment was roomy, light and well equipped. He let us check in a few hours before the official time.
The location is awesome. Right next door to the Museumkwartier.
You can rent city-bikes right on the corner which we definitely recommend if you want to explore further than the centre.
Maybe a point for improvement: The bed was ok but the pillows were a a bit small and not well filled, and the duvet was also a bit on the small size.
There was a definite smell of smoke in the apartment but it wasn't clear if it was from the renters before us or from another apartment.
Apart from these small things we were very pleased and would certainly recommend this location!
