I booked Javier's apartment for my mother and her friend who were visiting Berlin for a few days. They told me the apartment was perfect. Really comfortable and within easy walking distance of the centre of town. Javier was extremely accommodating and arranged for their bags to be stored between the morning they had to leave the apartment and their afternoon flights. If you are looking for a convenient and comfortable base in Berlin, this is the place for you! Thank you Javier!
