The apartment is ideally located to the centre - We were staying as we were running the Berlin marathon and the start line was so close and convenient. The apartment was clean tidy and very big - they could almost do with a few more things to fill it up as it felt a little empty. Our only negative was that we were charged 70 Euro for loss of one set of keys - obviously you would expect to be charged for loosing keys but we thought 70 Euro was a bit extreme considering they cant cost more than 15 Euro.
