This is more of a rented apartment than a hotel. Overall, the experience was good. The room was very nice, comfortable, and spacious for a studio, everything was brand new and clean when I arrived. Little things like a faulty kettle were promptly taken care of. The staff was efficient and helpful, there is a tablet that you can use to chat with reception.
There was a complete set of dishes, tea and coffee, a dishwasher and a washing machine. I requested an iron and it was brought the next morning.
There is a very nice lounge on the top floor with a rooftop terrace, where you can have complimentary coffee/tea/drinks in the morning and daytime. The view of the Zwinger and surroundings is beautiful!
Some things I can complain about:
They claim the rooms are cleaned on a weekly basis, I stayed 8 nights and did not get a cleaning.
The corridor near the restaurant smelled like dead fish, it got better after we told someone at the reception.
There was construction going on across the yard from my room, I was told it was not going to be loud as they are working inside the building, but it was loud. Trying to focus on work to the sound of a grinder is not my favorite thing.
There is no air-conditioning, it does get hot in Dresden for some time every year and I happened to stay in the hotel at that time. I am surprised such a new building did not have any air-conditioning, a fan in the room would have made it much better. The upstairs lounge turns into a greenhouse on a sunny day.
