We had a group of six couples and two singles, and the space worked out great for us. We enjoyed the common space for coffee in the morning and beers at night, and the bedrooms were separate enough that everyone had enough privacy and quiet. It never felt like there were 14 of us there at once, as there was plenty of space. We also enjoyed the easy access to downtown via S-bahn or tram. Would definitely recommend it for a large group.
