Heike and Alex were wonderful hosts, helpful, responsive and accommodating.
The apartment is beautiful, it's in a historic building with an elevator that looks like a prop from Wes Anderson movie. It's very centrally located. When you stay there, you are surrounded by beautiful architecture, great cafes and restaurants, and lots of upscale shopping. It's also only a couple of blocks from a market and a beautiful flower shop.
We stayed for a month and the place had all the creature comforts we needed: full size oven, good coffee machine, washer/dryer, dishwasher.
Would love to stay there again in future. :)
