5 out of 5 stars. Sirdin was very helpful in our stay in Berlin. He met us on the street when we had trouble with directions to show us where the apartment was. Our coffee maker was not working and Sirdin immediately brought us a replacement and gave us a bag of coffee and chocolate to make up for the inconvenience. The apartment was as described, very clean, and fit a lot of people with many individual beds. I would definitely recommend staying here for any trip to Berlin. My only small complaint was the noise level. The traffic and emergency vehicles during the day and at night were a bit loud. Sirdin was very aware of this and provided us with earplugs for a better nights rest.
