We loved the design of the flat and the balcony for enjoying some fresh air. There are some great restaurants just outside the building which was extremely useful and gave us a chance to enjoy local german food. The location is not central but good as it is extremely close to the underground, which takes you to lots of central places in less than 30 min. The main room was a good size and comfortable for our group of 6, and we all found our beds comfy also. The flat was clean and tidy on our arrival.
A couple of issues came up during the stay (only 2 towels between 6 people the first night, we could not get the kettle and coffee maker to work) but the host did respond to these.
