The flat itself is immaculate, clean and nicely furnished, the air conditioning was very helpful in the heat. There is everything you need and the beds are comfortable.
Unfortunately, we had to sleep with earplugs even though the windows were closed, because the bar across the street was very noisy until late in the evening.
The area itself for us was not very attractive and for our taste quite far away from the city centre, you lose a lot of time in public transport. I can't confirm that you can get to the historic district in just a few minutes, as described in the advertisement. It actually takes about 45 minutes to get to most of the sights in the city centre, unless you want to visit something that is directly on line 8. So it's not really possible to go back to the flat in between sightseeing to relax.
Unfortunately, I also missed a reception in the flat, where we would have been given some tips about the surroundings, I think, that would have been helpful, we only got the keys from the cleaner and didn't get to see our host. But it was nice that we could leave our luggage in the flat in the morning.
