Javier was an amazing host! He allowed us to enter the apartment early and just wait on the balcony as he finished cleaning. He explained everything in detail. His apartment was spotless, modern, comfortable beds and all the appliances you would need. I wish we could have stayed longer! Very close to public transportation. Close to the Berlin Wall. Very quiet at night. Overall a great experience and I would return again to Javier 's apartment next time I'm in Berlin!
