Very nice flat, clean and well located. It is not always easy to get hold of Harry but he made sure that the flat was nice and ready when I arrived. I stayed there a week for work, and didn't have any issues during my stay so didn't need to reach out to Harry at all.
I saw some comments stating that wifi was not working but I didn't have such issues.
The flat is well located, close to the Opera and there are a few tram and train stations nearby.
Would recommend :)
