We really enjoyed our stay at Markus' place.
The apartment is very nice and clean, well furnished and equipped with everything one could need during the stay (even a longer stay).
We appreciated proximity to metro station and the fact the apartment is well connected to all the city attractions.
Markus and Matt are super-friendly and helpful hosts, highly responsive; providing useful information even without being asked.
In a nutshell, we would definitely recommend this place and its hosts! Love to come back here sometime.
