Fredericke and Tobias' place is fantastic! We stayed for 4 nights in September. The room is very comfortable and clean. The apartment is located in a very quiet neighborhood and only a 5 minute walk from the St.-Quirin-Platz U-Bahn Station, making it the ideal location for us - as we prefer being able to have a quiet place to go after exploring during the day. Fredericke was also very understanding and helpful when our flights were changed last minute because of the mess at Schipol and responded to my many messages while we tried to figure out just how we were getting home. We definitely recommend staying here!
