It is everything you could wish for, for a pleasant stay in Berlin. It has got all you need in the studio. The decoration is a bit sparse, but you're not there to be in the apartment. It is quite noisy when you sleep with the windows open, as we are used to.
Great public transport links to the center and beyond. Nearby there's a delightful anarchic oasis in the city for food and drinks on Holzmarkt 25 ( a 5 minute walk). We loved it.
Berlin is not the most beautiful city in the world, but we saw some lovely spots and it is very vibrant.
