My best friend and I met in Berlin for holiday, and really enjoyed our stay at this place! It's a big space, and it's used quite well, and it's in a nice boho-chic kinda location. Very hipster melting pot type of neighborhood and somewhat central. We had a couple minor issues with the place:
-we went to heat up some food and make some soup and the kitchen supplies weren't really clean. Only the likely recently used glasses were very clean.
-we were asked to clean all dishes before we left, which is fine, but we would've rather been asked to just place things in the dishwasher for the person who cleans to sort out after. Why should we spend time cleaning when we're charged a hefty cleaning fee, and some things were dirty when we went to use them?
-So many airbnb's these days are fully furnished with everything from ikea. We recommend investing like $100-200 in new linens (the bed had a sheet on it with holes in it). Nicer towels, sheets, and pillows make all the difference!
-We were in Berlin during a heat wave, and there's no AC anywhere so it was very hard to sleep at night. Maybe store a fan or two in the closet for guests to use when it get's that hot.
