I stayed at the Guillaumes place for two nights and enjoyed my stay. The place is exactly as in the pictures and located in a lively neighbourhood where one finds cosy bars in every corner. The host was really quick in replying the messages and was really hospitable ready to give tips to Berlin and suggest things to do. The apartment itself is as in the pictures, decorated with style and very spacious. One founds everything needed for a short stay. Would recommend this for single or couple travellers.
