We stayed in Berlin with a couple of friends for five days and we had great time staying at Kate's flat! Unfortunately we didn't have a chance to meet her personally, but everything went very smoothly! The flat is clean and comfy, we had plenty of space for three of us. All the essentials are in place. There is no internet in the flat, but plenty of places to catch wi-fi close by, which is more of advantage as you don't spend too much time at home seeding the web. Also the location is just great, main u-bahn and s-bahn stations, buses whatever you need. The area is rather trendy with major shopping centers, supermarkets, restaurants, cafes and hotels nearby. Overall great experience and highly recommended!
