This is a nice 1 bedroom flat in a nondescript residential neighborhood. The bus stops right out front (if you know how to buy tickets from the driver or already have a ticket) and a 5-7 minute walk to the U-bahn. I paid a higher price than I would normally in order to be right in town for a short visit. The flat was clean and comfortable for our stay, but I would not use the adjective luxurious (but I have no comparison in Berlin, nor most of Europe for that matter).
