Javier and his apartment are wonderful. Javier checked in to make sure we arrived ok. Also, when asking if he could recommend a transport company for departure to the airport at a very early hour, he kindly called and made the reservation for us. The apartment is incredibly clean and comfortable. It is in a great location....just outside of the city enough that it is quite, but close enough that everything is convenient. The apartment is very cozy. I will definitely stay here next time I go to Berlin and would highly recommend to anyone.
