The location is great and very convenient, and overall, the place was OK for our short 2 nights trip. The instructions were absolutely clear, and getting into the flat was no hassle at all.
We had some minor issues with how the place was cleaned before - e.g., glasses were dirty, and we've found some crumbs on the oven pan. What was not that minor, though, is that in the description it's not mentioned at all that a Junkers gas heater is used for heating / hot water, and it is in the same space where the beds are! So, we ended up waking up five times during the night when the heater decided it's time to kick in.
