Sebastian and Phillip are kind, respectful, and communicative hosts. I stayed here for a full month and I would recommend this place for both short term and long term visits!! The penthouse is centrally located so you can walk to many attractions on foot and is also very close to two U-bahn stops. The room was a nice size with plenty of storage space and a large private bathroom along with a private entrance/lobby. The air-conditioning was a big plus given the summer heat as was the terrace. I highly recommend staying here and I hope to stay here again during future visits to Berlin!!
