Trudy's apartment is lovely. It is spotless, with everything you need in a home-from-home. We had loads of space and everything we could want. There were 4 of us (a couple and 2 singles) and the place was really spacious for our group, with a great living / dining / kitchen / space to relax and eat in. Also the roof terrace is a lovely place to start the day with a coffee, relaxing on the sofa. The location is great, a 2 minute walk from a train station, and we didn't find it noisy at all. Check in and all communications were easy and efficient. Everything has been thought of which made for a very easy trip. We will definitely check if Trudy's apartment is available when we visit Berlin again.
