Javier gave us quite a fright when none of his phones were on our arrival date! but there he was, smiling, waiting for us at the apartment, He was very helpful in showing us the ropes. The apartment is very conveniently located, 5-10 minutes from Oranienburger Str and 10-15 minutes from Museum Insel. The apartment was comfortable , modernly furnished. It is remarkably quiet and the bedding is excellent, which goes a long way by us. We found lots of guidebooks and maps. Our friend stayed in the living room and was independent since Javier gave us 2 keys.
There was also a a computer with an interenet connection which is nice,
