Great apartment, very nicely furnished, beautiful use of the space.
As mentioned in other comments there is no lift and the staircase is very steep. Not for people with weak legs. But once you are up there, you are rewarded with a great view over the city.
The only slightly negative aspect (but one which is out of Gordon's hands): we love to sleep with our windows open. That was not possible, because in the evening the (maybe not very clean) extraction of the restaurant/ bar below sends the smell of fried oil into the apartment. So we had to turn on the air condition to get "fresh air".
