This was a great apartment to stay in Berlin. Had all the basics for a great vacation in terms of amenities. Location is very good, too. Very close to tourist attractions like the Brandenburg gate, checkpoint Charlie, museum island. There is a supermarket just downstairs, which is super helpful. Frank was very helpful getting us started with tips when we arrived late at night.
Only 2 minor issues we had were the internet, which was frustratingly slow mostly, but sometimes sped up. Most often late at night. The second were the beds. As a party of 5, we were a little crammed. This did not matter to us since we were a family of small people & had no problem sharing a large double bed with 3. If your travel buddies aren't that close or appropriately sized, you might have trouble fitting in 5 in this cool apartment. Recommended!
