In Germany average rental prices are lower than in GB. For a monthly budget of $1500 you will get a big list of apartments of any sort.
That rule will work even for Berlin. Here the cost of centrally located apartment like one on the photo is about €1250 ($1400). This is a fully furnished flat in a quiet area in Prenzlauer Berg. The apartment is just a stone’s throw from the center of East Berlin. It has one bedroom, a spacious living room, a kitchen and a big bathroom.
