Our stay was really nice. The kitchen is fully equipped with all the cooking utensils, there is a coffee machine and orange juice maker, toaster and gas cooker.
Living room is large: has furniture and music player, and downstairs in the basement there is a spacious bedroom.
All was good, place is lived in, real and authentic with a selection of paintings on the walls.
The only comment is about the Internet. We were looking for a flat in Berlin and doing general research for our stay. It was very slow. It kept going on and off and it took us way longer to do something that could take a few minutes because of interruptions. But if you get an extension from Aldi that is down the road - you could be ok.
The place is conveniently placed near Mitte with easy access to all parts of Berlin.
All food and convenience stores are around. Claudia was very quick to respond and communicate with.
I would recommend Claudia's place for stay, it is a great size for a price, just the internet needs a bit of an upgrade.
