Very good place to stay for larger groups. It was perfect for our group with ten people. Very clean and very nice bathrooms and bedrooms.
There was enough space in the "living" room including the kitchen for our group. With 14 people it could get a little bit tight, but in my opinion still enough to sleep and to have breakfast.
The service was excellent!
Right around the corner there is a nice restaurant Nota Bene. Also a karaoke bar next door to the flat. On our arrival day we drank a few beers there.
