We've stayed for a week at Ilona's and Milana's place as part of our relocation to Berlin. It was not our first time in the city, but was surely our best experience by far. Both, Ilona and Milana were always super nice, flexible and, happy to help when we needed it.
The place itself is super comfortable and well equipped (plus: everything was brand new!). When it comes to location, we found it perfect for everything we needed. It's in a calm area of Charlottenburg, which means that you can easily relax there after exploring the city but within a walkable distance from bars and restaurants. When you stay here, don't miss out on the sunset at the Schlossgarten, it's amazing and just a couple of minutes from the apartment.
Places such as this one are a rare find in Berlin. If you got lucky and it's still available for your days, don't think twice before booking it!
