This flat is a part of an entire building of flats all for rent. The location is very convenient to both Hauptbahnhof and Karlsplatz stations.
For the price, the building and the flat are rather run down. WiFi worked intermittently; the kitchen hot water wouldn’t turn off; the air conditioner required that you manually dump out a water bucket twice daily; the entire place was a little crufty. Towels were permanently stained and rather disturbingly brownish in various parts.
That said, checkin was very easy and the host was also easily reached. The location is great; perhaps at half the price, the flat would be a good deal. As it stands, the quality level was worse than I expected, especially compared to the many flats I’ve rented throughout both Germany and Europe.
