The flat is really close to the Belvedere, just a couple of blocks away. Also 10 / 15 minutes walking from the Opera / the city center and the subway.
Bed was comfortable, kitchen has everything that you need and there's also two markets close by.
Although it is in the first floor, there's an elevator to help with the heavy luggage.
The flat looked great and it was ample. The TV has access to Netflix so thats a plus.
For the most part the surroundings where very quiet.
Only complaint would be that the host / host representative was slow to respond.
