We had a great time at carolina's apartment and she provided lots of touches to make us feel welcome such as milk, fruit and coffee for the mornings. The apartment was clean and lovely fresh towels provided. For us the apartment was in a great place as it was close to friends living in Berlin but it's also really easy to get to the airport and nearby tram, plus the cafes and bars near kollwitzplatz are great. Carolina was a friendly, responsive and warm host, I recommend it!
