The best response time and attentiveness to my requests was with 'Team Richard'. Such speedy and enabling replies, it was just great to know that they had me covered all the time with any information I needed.
Do pay attention that you must have the option to make a call for the opening of the building door.
The apartment was quite big and roomy, the beds were comfortable. If you are a group of 5, one will sleep on the sofa. The 2 rooms are very quiet, one of them is huge.
The kitchen was packed with all the necessary kitchenware. One thing to mention is that they do not supply toilet paper for example, you will need to buy them separately (self catering apartment).
The location is quite good and on the west side of the inner Stadt/ Old town, close to the university. The apartment was clean and comfortable, and the kids had Netflix.
To conclude, we had a great time, location is very good, the apartment was bigger than expected and we liked it. I gladly recommend.
