It is really great apartment. The location is great, shops and metro are within walking distance, the popular Mustafa's Kebab and other Kreuzbergs popular spots within a 15 minutes walk. Martin answered all our questions and we had no problems with check-in and check-out. The apartment is in good condition, it has everything you need for a week or two. All the photos are true, all devices are working. The best price/quality ratio, which I have found in Berlin. I can only recommend this apartment by Martin.
