I had a fantastic stay and there are a couple of key callouts:
1/ Christian is an amazing host host; he goes above and beyond to make the stay an enjoyable one, and is really responsive with communication. He's also very organised e.g. he provides an online link to access instructions for use of the home facilities/appliances
2/ The apartment is a stunner: its really clean, modern, well decorated, has all the furnishing you expect, superb views of the city, and is in a really convenient location thats a skip away from the transport, parks, shops, and entertainment
I'd definitely recommend a stay if you get the chance!
