It was a very easy process for check in and check out and the apartment was very clean. A beautiful apartment in the heart of Berlin close to everything you could possibly need transportation, restaurants, grocery store etc. All amenities were excellent we cooked breakfast every morning and had all basic items needed. Hot water and heaters all through out the house made us feel very comfortable. The wifi wasn't as strong as we would have hoped but other than that the stay was perfect. Maria even has a list of recommendations for you waiting at the house which came in handy.
