We had a great time at Retro Design Mitte place and would definitely stay there again. Located right at subway station it takes you quickly to downtown core. Clean and spacious apartment and beautiful view from balcony. We found our stay very comfortable. Quiet and very green neighborhood. Close proximity to local restaurants and a supermarket. Local restaurants are really great and affordable. Although, the stair was a real challenge after whole day of museum visit. The internet was a bit inconsistent, not very reliable during our stay. When we arrived one of the beds was broken, and a coffee machine was missing. Hosts are supper responsive and had it all fixed very quickly. If you plan a trip to Berlin I would definitely recommend to stay here.
