This apartment is really perfect for a medium/large group. Some of my favourite things about this place:
1) There was one bathroom with a toilet and shower, and a second smaller bathroom with a toilet and washer/dryer. With a group it's so nice that one person can be showering in one bathroom and there's still another toilet available.. it made mornings a lot faster so we could get out the door and go site-seeing!
2) Patio with picnic table. We enjoyed eating pizza out there on warm evenings. :)
3) Lots of restaurants and bars nearby to enjoy (Caligari is great if you like Italian, and Keith's was a cool bar for whiskey lovers).
3) Fully stocked kitchen! So if you want to stay in, it's very easy to cook for yourself, all the cookware and utensils you could need are there.
4) Tempelhof Park is nearby and it's really neat, it used to be an airport and it's a wonderful open space. A great place to watch the sunset with a beer or two.
Overall we really enjoyed this place. Perfect for a group of friends or a family.
