Roi was a great host, always responding quickly and making sure we had everything we needed. Checking in was easy, we had champagne waiting for us in the room, and the apartment is located in a great area. There's a grocery store right next to the metro a short walk from the apartment. Passing the metro is one of Berlin's premier shopping areas. The apartment is very comfortable and the washer/dryer are invaluable. Roi also has a dishwasher which is unique for a European studio. Thanks for a great stay!
