The accommodation is really pretty and good. Most of all I liked that it is modern, stylish and is located in a very nice area close to the city center.
The only suggestion how to improve the stay probably would be to have some fan heater in the flat. There is an air conditioner in the flat, but I don't think you can warm up with him in the flat. Though, I think for the money paid it is indeed an excellent apartment.
They even have a welcome bottle of wine for each guest. It is really sweet and feels that they indeed are happy to host you.
