Super cozy, small, clean, light and quiet studio apartment. For a sofa bed, the main pullout is not bad at all, big enough for two to share without running into each other. However, getting the second bed out makes things very crowded indeed - best for two to share. It's in one of the cooler neighborhoods in Berlin, so lots of little coffee shops, bars and restaurants, plus parks to wander around in, which was great. Very up-and-coming trendy. This place though is definitely run professionally, even though it's in an apartment complex with locals, so if that's not what you want, take note - it's a teensy bit sterile.
