Wonderful, bright, spacious apartment! Much better than the photos, with high ceilings, huge windows, plenty of space, and well-kitted-out kitchen (dishwasher, big fridge, plenty of dishes, washing machine, etc.). Comfortable and warm, and amazing shower. Also one of the most comfortable beds we've stayed on (memory foam all the way) and loads of storage.
There are plenty of nice restaurants nearby, as well as an Italian restaurant right next door which was useful for the evenings we were too tired to go further afield. There's a little grocery nearby, and walking into the city centre takes only 20 minutes. The street is quiet and there is a park just opposite, so the views from the flat are all greenery (which also means total privacy).
Georg is a great host, very friendly and responsive. We had a late flight and he kindly waited for us to arrive (11pm!) which we really appreciated. He also has a fantastic craft beer bar in the city centre with an enormous selection of interesting beers and ciders. The only minor issue was the wifi (4mbs), as it had a spotty connection. However, Georg found a temporary solution after we mentioned it and is getting it permanently fixed as we speak. Lastly, it is on the third floor of the building and there is no lift, so come prepared if you have heavy bags. ;-) Thank you Georg for an excellent two-week stay, we really hope we can return!
