The view and the fact that you have your own appartment in a skyscraper made our stay a nice experience with a touch of exclusivity at a very reasonable price (ymmv as prices may have been cheaper during corona times). Most of the checkin/checkout and access to the building is fully automated and can easily be handled with the smartphone. All of this worked flawlessly. While we had an issue with wornout mattresses this might or might not be an in issue for you. From the level of service I'm pretty sure this is an exception and can be fixed easily by Elwin. But if you are sensitive you might want to reassure you that this was fixed.
Apart from this it was a very pleasant experience with a special touch you don't find easily in other places at that price. The pictures speak for themselves. Thank you!
