Had a fantastic stay at Jon's apartment. Never having been to Berlin, I wasn't sure which neighborhood to choose but in the end was so glad I picked this one. It's a great location---on the north side of the Mitte neighborhood, which means you're walking distance to museums but far enough away that the streets around the apartment aren't touristy. It's also close to Prenzlaur Berg, which has great restaurants and shops. Then right across the street from the apartment is the entrance to the U8 train line, which is only a few stops north of Kreuzberg, another cool area in Berlin. The apartment itself is so cozy and interesting. There are four big skylights which swing open to let you look out over the skyline and rooftops. The apartment is full of art, magazines, records and other cool things. Apartment is on the top floor (I think sixth floor) with no elevator, just to warn you. The shower is great---great water pressure and plenty of hot water. Plenty of heat (we were there in winter) and it was warm and cozy. Other reviews mention this is on a busy street, but the apartment itself was nice and quiet, and taxi drivers knew how to get there. Jon was easy to communicate with. He greeted us at the apartment and gave good suggestions about neighborhood restaurants and sights. He was also really responsive during the trip if I had any questions, and check-out was easy. Would definitely stay here again.
