Amazing and very clean flat! It is very spacious and there's even a sofa bed in the living room area. In terms of breakfast, there were a selection of teas available and all the basic kitchen utensils to make your own food if you want to. There's a supermarket nearby too (Rewe).
In terms of location, public transport is easily accessible and took about 15-30mins to most of the attractions.
The only problem we had was a very late check-in and we had to wait 40mins to finally get into the flat. I think this was a logistic problem between the host and the lady in charge to open the flat for us but some sort of compensation for this wait would be appreciated, especially as my auntie was having really bad back pain at that time and to wait in front of the door that long was not very pleasant.
Other than that, the flat itself was very good and we would definitely recommend!
