Julieta's apartment is just gorgeous. It's a big open space with a colourful and pretty interior, high ceilings and big windows (through which the morning sun shines real nice). Of course when you want it to be dark when laying in bed, the curtains do a great job, so no worries you'll be woken up by the sunlight if you don't want to.
We also haven't noticed any noise from the street when we were there, so that helps for a good sleep as well :) Oh and the bed sleeps very good too.
The kitchen is very practical and has everything you need. The bathroom is quite small but very efficiently designed and even has a nice bath.
Last but not least, the location is great! Very close to the Tempelhof and close to many great bars and restaurants, concert locations, etc.
Would highly recommend her apartment and would definitely try to book her apartment anytime I go to Berlin.
